Borrowing an idea from John @ DC Birding and TG @ Science and Sarcasm, these are the states that I have made it through. It helped spending 20 years in the Air Force and 3 years driving truck cross country. I'll make it to Hawaii when they build a bridge I guess. I like how they put in the square with Alaska,"not to scale". Let me translate, it's about 1/4 scale.
There's still a few more countries I need to make it to.
