The chapter I belong to in Minnesot has food plots on most of there WMA's. They use the money they make to help with events they hold. They also keep some of the corn for winter feeding. If food plots are done right they should not cost anything they should turn a profit that will further help the orginization.
Agreed. I'm assuming that there are some member farmers in most chapters who donate time and machinery use for the planting/harvest as well, which cuts down on overhead cost tredmendously.
