I created a
map that shows the approximate location of all the beta test teams.
The closest teams seem to be 151, 811, and 1073. 330 and 294 are also very close, and there are 3 other beta test teams within a 2 hour drive. There are also 4 teams pretty close in eastern PA and NJ.
California has the most teams, 6, followed by New Hampshire and Virginia, 3.
Only 3 of the teams have won the championship chairmans award, down from 6 last year.
