If you can get a ride from someone and park on the road before the salt starts, that works best. There is a rush in the morning to get in and finding a lift from the entrance was never difficult. My wife and I hitched a ride from a nice couple that had driven up from Texas and we got a ride from two long haired freaky people another time. Nice folks and everyone is giddy so it's nice and friendly. Second, the sun's rays are reflected by the salt and you get sunburn in unexpected places. Just slather the sunblock on everywhere you don't want sunburn. Bring way more water than you can imagine drinking by yourself. The heat can be intense. Ice is even better. Bring a hat. Do not go to the Bonneville Salt Flat WITHOUT A HAT! Finally I think it is important to remember that these fine people have waited a long time to be on the salt and many have traveled across the globe. This may be there only shot they'll get this year to make something happen. It may be the only shot they'll ever get... All the work, all the planning, all the money? It comes down to one week. It is an amazing, beautiful expression of humanity. Have fun!
