You could try to build a better varmint and hog proof feeder (I realize feeders aren't legal in all states, but they are big business here in Texas). Many ranchers/hunters have issues with coons and squirrels climbing the legs and emptying the feeder by spinning the plate...even with a cage around it. Also hogs knock the feeders over and tear them up to get to the corn. Finally there is the issue of filling the feeder. Winch style feeders allow you to lower the feeder however there are many fixed leg corn and protein feeders that can not be lowered and must be filled over the top. A clever economical, fixed or portable system that is mechanical or battery powered that would keep the hunter safe (rather than standing on a ladder, on their UTV, or in the bucket of a front end loader) would be great. Just a few ideas.... Good luck
