Bargon, you didn't mention what limits you were interested in, but my choice would be LA. Nothing to do with the aesthetics of either city, it's just that there are games at your level always going at Commerce, the Bike, etc. I go to Vegas about three times a year and find I often have to wait until certain times in the day to get into a game: At Commerce, anything from 1-2 to 40-80 is going all the time, and your wait is rarely longer than 10 minutes.

Good luck.
