I most recently went on a crazy road trip across five states. I started in Washington, went through Oregon, Idaho, Utah and Wyoming. Most of that drive on Interstate 84 is nothing but desert. Crazy boring desert. There is also a lot to see -- even in the desert -- but, sometimes when you get a little drowsy from driving and seeing the exact same sagebrush for 700 miles.
That's when you have to stop at a rest area. They are all there to give you a little respite, but some of them are much nicer than others.
