Joining another bandwagon. I've been to 47 states! My mom and I have taken 3 cross-country road trips, and I have family almost all over (some used to live in Alaska, so we definitely went to visit), so I've done pretty well for my 26 years. I even posted about one leg of our 2007 trip a while back--read about it here and get inspired.
I'm missing Hawaii, Utah, and Vermont. Unfortunately, I don't think those will all happen in one trip. But I have a friend living in Vermont right now, so maybe that will be next?
