Camping at the Gorge kind of sucks, but if you keep expectations low it can be a good enough time. Strongly recommended that you keep drinking because it's much less good when sober. Last time camping there (Jimmy Buffett) was the last time I'll camp there, but it was bad luck. Got locked out of the car and spent the night in the passenger seat of a friends car that was about 3 feet from the honey bucket. All night long, the hollow sound of urine stream on plastic. Also nearly got in a fight with a crooked security guard and I'm one of the least belligerent people you'll ever run across -- it ended well, I stayed and the security guard got booted from the grounds. Good times.
As far as Seattle goes, probably head up to Belltown. Get Ed to hook you up. Nite Lite's my favorite dive bar there -- though not necessarily the best pick up spot. Tons of places on first in Belltown -- other streets as well, but start on first.
