Followed a good blood trail to a spot with two fist sized spots of blood (about 200 yards). Then, nothing.
I find this strange. Did you hit her low or high? I'm guessing low........200 yards is a
long way for a deer to run with an arrow in her boiler room. I only ask because I wonder if the shot was as good as you first thought it was. I'm not doubting what you say, just what you saw. She might not be as mortally wounded as you think.
If the guys won't let you cross, IMHO, you have no option but to comply and call it a day. Tresspassing is not a game you want to get started. I'd definately keep a close eye, and if I caught him tresspassing on me to find a deer he shot, I'd have him prosecuted.
