My only advice after surviving 15 years of opening days while living on the edge of a state forest, is to post your No Hunting signs so that the line of fire through them doesn't intersect with your house or barns. I had to buy nearly a dozen new signs every year after our local "sportsmen" used them for target practice, and I always liked it better when the errant shots hit the adjacent woodlot rather than my garage or outbuildings.

I had perhaps a dozen encounters in those years with unwanted hunters on my posted property. I am not a physically imposing specimen (well maybe to third graders) but found nearly every one of them would leave when asked/told, especially after noting that small children lived there. To those who wouldn't, I just pointed out that they could stand and argue with me all they wanted, but that when I had left the house my wife had recorded their hunting license numbers and had called the county sheriff (which was always total BS), so they had better hope their argument would be shorter than the sheriff dept. response time.

Eventually we got a reputation as the House where the Bleeping Mother-Bleepers lived, and they chose to hunt elsewhere.

Short of continual confrontation, which has it's obvious risks, the bow-hunter idea is your best option.
