We are fortunate to have some of the biggest hearted pondmeisters in our midst in the form of Eddie Walker (who sponsers events with church groups at his pond), Norm Kopecky (who sponsers fishing outings for folks with limited mobility...hope I presented that "PC"), and Nate Herman and his project to do exactly what you speak of...a kids fishing park.
There are others, and I hope that they speak up and are recognized for their efforts to "give back".
