I really don't know yet where I'll be coming from. Earlier today I was thinking it would be West Seattle. Then it was going to be the U-District. Now I don't know. Still might be either West Seattle, or the U-District. Could also possibly be Renton. Or maybe something else entirely.

It'd be nice if it was Renton as it's a lot closer to Portland, and I know I'd be getting off at least 1/2 hour sooner if I was there.
Anyway, the 3 1/2-4 hour quote was taking traffic into consideration. I know I've gotten down there in about 2 1/2 hours before. But that was no traffic whatsoever. And it was a good 5+ years ago.
5 South sucks all through Seattle at that time of day. Is also no fun from Fife down past Tacoma. It can also be a little lame around Olympia.
But, I've got both your cell #s now (would be nice if I had a cell myself). And am printing up all the info I need...
