I used to fish a pond that was in the middle of a trailer park for retirees. It was loaded with 2-5 lb bass, giant crappie, and bluegill in the 12 inch and up range. You had to have permission from one of the residents to fish there, so it got very little pressure. Unfortunately, it suffered a severe Winter kill about 10 yrs. ago and never recovered. The pond is still there, but now it is overrun with nothing but stunted, 3-6 inch bluegills and crappie.
