Prague is one of my favorite cities in the world! Have you ever tried the free walking tours of the city? I did it the last time I went and it was enjoyable (albeit long and way behind schedule). There was also a very good public music festival in the main square going on when I was there.
Also, thanks for the pictures at the Museum of Communism. I've been twice and wanted to go both times, but it just didn't work out.
I take it y'all didn't go to the seven-story club, Karlovy lázně? Some of my best memories (that I can't remember) are from that place. Good times, good times...
