Just get about $100 worth of snacks and plenty of Gatorade and Red Bull. You'll make it in no time. Just watch out for the state troopers. Nice guys, but they will write you a ticket faster than a slot machine will take your money! Seriously, it can be a monotonous drive. The northern part is a little more scenic, but the southern end of the state is a desert, and is mostly flat and filled with sagebrush.
