I figure I'll go to the Belle's rally in Portland the weekend before, hang in Portland an extra day or so, and then take a couple of days to drive to Denver. That would get me there in time for the early festivities. Then it's just a couple days back to Seattle just in time for my birthday, on which day probably nothing exciting will really happen, but that'll be ok, cause I'll be all worn out.
It's an interesting prospect... I gotta think about it some more I guess.
