(Map source)

Above are the states I have been in. Many of them were just quick drive throughs.

It's been a while since I got out and explored America. California is the only new state I've added in the past decade.

But I assume someday I'll get out there again. Which state will be the next to fall? If I had the extra coin today and the opportunity to escape for a couple weeks, I'd load up the Madone and test my metal on some of the big mountains in Colorado (here or here) or Montana (here or here). In that event, "nearby" Utah or Idaho are strong contenders. On the other hand, New England is shorter trip. If the history bug strikes again I can kill four birds with one short stone's throw.

Time will tell.
