In chronological order for me:
1) Antonio: in Atlanta, Georgia. We spent about an hour walking around the downtown area and talking.
2) Swedish Cheese: in Lund, Sweden. We walked around Lund for about an hour and then spent the whole evening in the pub having a couple of drinks (I'll never forget Swedish prices!)
3) Kalwejt: in Warsaw, Poland. He gave me a walking tour of downtown Warsaw and we then proceeded to have a couple of Polish beers before I had to get back to the airport.
4) Grumps: in Pittsburgh, Pennsylvania. We met at a brewery and enjoyed a couple of cold IPAs! (He isn't all that grumpy
)
