[emathias]

I haven't visited the most places, but I am one of only four people who've taken the survey so far who've been to both the city with the most of us to have been (LA), and the city with the least of us to have been (Moscow).

Beijing
Barcelona
Los Angeles
Moscow
Helsinki
Paris
Stockholm
St. Louis
Salt Lake City
Oslo

If I counted airports (which I didn't), I could include Amsterdam and Mexico City, too.
