Yea, sorry we don't have airball up every Saturday and Sunday like we used to, we just got tired of the grass and airball field being all destroyed from the constant wear and tear. The bunkers can be washed, but the grass was just getting pretty thin with the constant abuse.
Now we generally put it up every Sunday, March - November, and when it is up, it is pretty perfect. The grass thanks us
Feel free to give us a call before you come down and I'll let you know if airball is up that day. The guys from STL Xtreme are doing and amazing job of setting it up right when it is up, and they are on the list for the 2012 upgrade kit.
As far as a field in STL that does do it every weekend even in the winter, I have no idea anymore... I'll let the others chime in.
