Chico,
I have checked on the number of players at the YMCA's in Greenville in the past. Unfortunately, I don't remember the numbers (which I know to be in the several 100's), but will attempt to retreive that info. Also, there is Upward soccer. I have no clue as to their numbers. There are several churches in the Greenville area that run the program. I do know that the numbers for Upward basketball were pretty large. The Upward bball program my son played in had about 10-12 teams of 9-10 players in the 3rd/4th grade boys league alone. I would guess that the soccer numbers would be slightly lower.
