I woke up to the dog barking this morning, and as I was leaving for work, I spotted an orange vest in the 5 acre woods behind my house. I hung around for a bit to see who it was, and it turned out to be the property owner's son-in-law, his son, and his daughter's fiance. Now, I only own the house I live in, not the ground it sets on. I would like an inconspicous way to make it unpleasant if not impossible for the hunters to pass through my yard on their way to the woods, which is about 20 feet from my house. Any ideas? I'm afraid to put food out for the critters, since that would make them more easily spotted.
