Also worth noting that in these Northeastern cities the center of the fan bases aren't necessarily in line with the center of the population. If the Red Bulls wanted to place their stadium where it would be most convenient to their larger base they would have placed the stadium in Westchester County or Greenwich, CT. In the Boston area they would put it in Metro West, Somerville, or Lexington. I don't know enough about DC to know the proper suburban setting for a SSS, Bethesda maybe?
