Whatever you do, DO NOT FORGET YOUR CHARGER!!! You think you hate long road trips, try having your smartphone or handheld gaming device and it go dead on you, way before you get to your destination. It'll be like it's mocking you, when you can't turn it on, but you have it in your hand. All the way to Wally World.
I remember as a kid traveling by car each person would pick a number from 0-9. As vehicles pass you, the last number on their license plate matches yours you get a point. If its a double of your number, two points, etc. It does pass the time but beware if the driver plays, they tend to keep slowing down and passing the same car that has their number :-) Hope you have fun with it!
if you have an ipod fully charge that and you can listen to music or something if you have a movie player take some good movies take a nap lol take your cellphone if you have wi-fi go on ask talk to ppl talk to me JK thats all i can think of 4 now wait... maybe play some games lol
listen to your favorite music and bring along a good book or fun game. The alphabet game is fun: try to find the whole alphabet on signs on the sides of the road. or if you have a Ipod touch of some kind charge it before you go so you can play your favorite apps. :)
