I'm a bit directionally-challenged, so when I'm in my car, I tend to cling to my Mapquest directions or road atlas. I've actually absorbed surprisingly little knowledge about the nation's highway system, but from what I hear, it all makes a lot of sense. Put your highway knowledge to the test - I'll give you the name of an American highway and the state one terminus is in. It's up to you to choose the state on the other side. Get all 15 right and I just may offer you a job as my backseat driver.
