Have you seen the decoys some people are using to hide behind, and crawl up to toms? I've seen some in action online, and they work unbelievably well, but that's CRAZY! Looks like a great way to get shot to me. I can't even imagine using one.
We have some folks here that like to use rifles, even though they're not legal. Some of them "hunt" from their vehicles.
I doubt I'd last long crawling around in one of the fields I hunt, holding up a tom turkey decoy. Posted signs don't mean much to some of the people around here either, so that wouldn't be much insurance.
