I havent ran in to this yet with turkey hunting. I have seen it many times during deer hunting. I grew up on a farm so we had our own land to hunt. When we sold the farm and moved to town we had 100's of acres of city owned land (outside city limits) to hunt. We hunted this for years and nobody else hunted it (I think everybody thought since it was city owned it was considered "in the city"). We did check with the chief of police to ensure we could indeed hunt it. Well that came to an end when some jackasses decided to go mudding with their trucks on the property and tore it all up. The city then closed it off.
Now we struggle to find land to hunt. Each year we lose more and more. People have gotten the idea to lease their land to make $$. They are able to do it as people who can afford it come from the big cities to hunt it. We have tried public land and quite frankly I would rather stay home. People act nuts on the public land during deer season...at least here in Wisconsin, Im not sure if it's the same way elsewhere. I had a bullet whizz by me 2 years ago after some idiot (who knew full well my location, he watched me walk to where I was and I was dressed in blaze orange) began shooting across a field at a deer. We have had verbal confrontations with others who feel the land is "their spot", one guy last year began yelling because we shot a doe (in a herd management unit, i.e. doe tag). I try to avoid public land as much as possible during deer season. It's really too bad and I wished I could afford to buy my own land. I remember being younger and struggling to sleep the night before the opener out of excitement. Now I dont really look forward to it much at all. Thank God turkey hunting has filled the excitement I used to experience deer hunting.
