In my neighborhood...

We have a sports complex (3 baseball fields, lacrosse & soccer fields). It is on donated land that is managed by a recreation commissioner. I am on the board and am one of the commissioners of said field. The fields are intended to only be used for youth sports, but it is seen as a community resource and generally everybody plays nice. We have a big sign at the entrance listing field rules, one of which is no dogs allowed. Right next to the sign we have a dog poop bag dispenser, which we maintain and supply.
