In one sentence, describe what the following article is about: When you get wrapped up in all the grease and machismo floating around at the strip, it can be common to forget about the most essential part of drag racing: surviving it. Make sure that you're aware of everyone on the track, around it, and stay focused on completing the run with safety. If you feel unsure about racing, unconfident in your vehicle, or uncomfortable with the track conditions, pack it up for the day.  You need to always have your vehicle inspected before drag racing. Blowing out a tire going 120 mph (190 km/h) is extraordinarily dangerous, and turning out of a skid at those speeds can be deadly. Use extreme caution. The Snell Memorial Foundation was founded by William "Pete" Snell, an amateur auto racer who died in a racing event in 1956. His then supposedly state-of-the-art helmet failed to protect from passing away, and a number of his fellow racers, colleagues and friends came together in an effort to improve the design of helmets along with their capabilities. They're now considered the standard in the field. If you're going to drag race, you need one. The ideal time to shift is when the descending power curve for the lower gear crosses the ascending power curve for the higher gear. Most drag racers will use a tachometer to closely monitor the RPMs and feel for that sweet spot, just before the RPMs hit the red patch on the gauge.   Many drag racers will use a lighted tachometer, which will flash a light indicating the optimal time to shift. Great racers anticipate these lights, however, shifting perhaps 200 or 300 RPMs before the "ideal" time, to make the action slightly smoother. Drag racing in automatic transmission vehicles exists, but is less common. Manual transmission vehicles offer faster acceleration times if you can get the technique right. If you want to get into drag racing, practice your shifting in a manual transmission vehicle. If you want to really grip the track, you need to get some racing tires for your vehicle. Without tread, heading up bald tires will allow you to grip the track and increase the efficiency of the engine.  Contrary to popular belief, keeping the tires a little low doesn't help improve your times as much as once believed. While it does increase the surface of the tires by a small degree, keeping the tires too low can cause the interior wall to wrinkle, having the opposite effect. Keep the tires inflated to the low end of the proper specs. After several runs down the strip, you should start to notice some build up from other cars' rubber and exhaust developing. That's the sweet spot. Bare asphalt won't have the traction that this coating of rubber has. Stick to the groove and barrel down the track.
Summary: Always put safety first. Invest in a Snell-certified helmet. Shift at the correct times. Use bald racing tires inflated to the proper specs. Drive in the "groove" created by other racers' tire slicks.

The reason for this is to have everyone in mind, which will prepare you to shop for gifts specific to each recipient as well as begin to plan out how much you’re going to spend. Write down each name, and if you have a specific gift in mind, include that as well.  Don’t forget yourself! Add yourself to the list and include everything you wish to get. Factor this into your budget. A good idea is to ask others if there’s anything from the country you’re visiting that they want. This will give you ideas, help you research the item for authenticity and price range, and make shopping easier. Set a limit for each person. When you’re out in another country browsing the shops, it’s very easy to go over budget. In addition, you have to factor in the costs of miscellany such as snacks and transportation, which also contribute to your overall budget and how much you can afford to spend on others. Currency exchange is another sneaky charge that affects your budget, as is your ability to ship all these gifts home. Before you go, figure out what a real, quality item looks like and what is an appropriate price for it. This way, when you’re in the midst of dazzling tourist shops and foreign prices, you’ll be much more likely to stay under budget without sacrificing quality.  If you want to buy a kimono in Japan, for instance, search online for what indicates a kimono as authentic as well as scams to watch out for. You can also search online or through guidebooks for tips on where to purchase your items. The key to bringing home a good gift is to get at the heart of what a person wants. The best gifts show that you care about a person, and to show that you care, you must understand the person. Keep in mind the person’s likes and dislikes and match them appropriately with the amount of money you are willing to spend.  For instance, if a person doesn’t like brandy, bringing a bottle of brandy home from France, no matter how expensive, won’t work. A successful gift will be one that makes a person think of you when they see it. This can be something worn such as jewelry, but it can also mean any other type of gift. If you don’t know the person well enough or can’t find an ideal gift, try getting them something that makes them want to travel. Even a stereotypical trinket such as a magnet or snow globe can mean a lot to the right person.

One-sentence summary -- Make a list of everyone you’re going to buy a gift for. Set an amount you’re willing to spend. Research the items you want to buy. Consider the person’s tastes.

Problem: Article: Your hands should be roughly evenly spaced -- if the ball was a clock, your right hand would be at 3:00 and your left at 9:00. It can help to shift them back a bit, too, so your thumbs are almost touching in the back of the ball. This helps you get a bit more leverage on the throw. Throw-ins only occur when the whole ball completely passes over one of the touchlines. The restart occurs at the point it exited the field of play . The rules for throws are not super difficult, but you should be mindful of them with every throw. Even the pros sometimes make a mistake, but it is no less embarrassing when you do it in a game. A legal throw-in must have all of the following elements:  You are facing the field of play Both of your feet must be on or behind the touch line. As long as part of each foot is on some part of the 5 inch touchline or behind it and touching the ground at the moment the ball is thrown, the foot position is legal. You use two hands The ball comes from behind and over your head. You cannot score directly off a throw-in.
Summary:
Pick up the ball with both hands, one on each side of the ball. Review the rules to ensure perfect, legal throw-ins.
