route 66

I've been trying to plan a road trip around the west for a few months now. I've been posting lots of questions on this site about routes to take, sights to see, that kind of thing.
Well, a friend of mine gave me a "bon voyage" gift and I'm totally confused. It's this folded-up paper thing -- kind of like origami? And it has this green drawing of California, Oregon, and some other states on it, and all these squiggly lines and numbers. I said thank you but inside I was like "what?" What is this thing and what am I supposed to do with it?

Oh please, not another stupid ass posting. We really find no humor in your map quiz.

Gee, I heard of those once in the days before GPS and all the fancy crap. I think they called it a MAP. If you study it carefully it will answer many of your questions regarding routes to take and things to see.

I thought the elementary schools were back in session this week?
