Jason Kottke talked about where he stayed/visited last year and historically, I've been inspired to do the same (here's where I visited and stayed in 2006), but for some reason, didn't do it last year and of course, I don't remember where all I stayed in 2007, but I'm sure the list would be similar to the year before as I keep visiting the same places over and over and over again. That said, I do remember a couple (and of course, the same rules apply; I spent one of more nights in each place and the ones marked with asterisks were visited multiple times on non-consecutive days) and so have combined the places I've been and stayed in '07 and '08 to the best of my knowledge:
Not a great track record for two years worth of travel, but I also visited Virginia, went to Delware, and spent time at airports in Baltimore, St. Louis, and Chicago. On the list for this year (both hopefully and in reality):
We'll see how it goes. I'll certainly keep you posted.
