That's tough. If it's legal to drive with that many people (it's not in Maine) there is little you can do. Sure you can talk to them but if these guys don't want of haven't taken the time to learn about there quarry and think driving deer is the easiest or only way to shoot an animal you in for an uphill battle. I wish you were close to New Hampshire. I posted my 50 acres to keep the neighbors out this year. What you've describes is exactly their game plan. They'd push the animals all over the place and I found a couple of unrecovered animals which was the straw that broke my back. If you were close by I'd say come over and hunt.
Personally I'd look for some private property to hunt. With public land your hands are realy tied IMO.
