Potential Travel Plans

So Tim mentioned that he has a plan to get a 2 week eurorail pass and go around all of Europe when our semester ends. I'm totally down (can you imagine, Geneva, Berlin, Copenhagen, Prague, and 5 other places?!) but I just hope that these plans will come through. Aside from this 2 week euro-extravaganza, I do want to go somewhere during the semester for one of my 5 day weekends. I have my heart set on Barcelona, but I really have to found out when and specifically with whom I can go. It seems everyone already has travel plans or enough friends around the world that they don't need any companions. I'm also considering St. Petersburg, especially during the white nights. I've wanted to see them ever since I've read Dostoevsky's short story of the same title (I know, literary reference, lame). I just want to see the city lit up at 3 in the morning! I don't really think that's plausible though. Hmmm, looks like I have a couple of things to consider.
