On a completely unrelated note, every once and while FLG recognizes one things that makes the DC area different -- helicopters. FLG will be driving across the Key Bridge and see tourists gawk at helicopters flying very low overhead. At this point, FLG barely even notices. Military helicopters fly up and down the Potomac so often it's no big deal. It's like a helicopter freeway.
One doesn't really see or notice helicopters all that much in other places. FLG guesses that there are probably a goodly mount in NYC, and perhaps the buildings are so high that it's difficult to notice.
