I also had a pretty good time wandering around on mass transit visiting friends for a few days afterward, although I didn't figure out that I wasn't in the most tourist-friendly part of San Francicso until the third day of me wandering around aimlessly when I decided to take the cable car and see if I could steal a menu from Ghiridhelli's to frame next to the one my mom stole in the 70s. Oh well, I had a pretty good time wandering around what was, in retrospect, probably not the nicest part of town for two days before I figured it out and I probably saved a lot of money on food and entertainment that way. I wish I'd had time to go to the aquarium I saw on the third day, though.
I also picked up some kind of stomach bug on the train ride back Thursday and I haven't shaken it off yet, so I've been kind of a lazy slug. I'll try to upload some pictures and expand on all this in a few days.
Now I need to see if I can somehow afford to go to Baycon and/or Westercon this year, as I have now decided that solo convention trips and train rides to California are something I can do.
