Sounds like you have the traditional guys who "reserve my spot". Is the land public--private? If it's private land you could talk to the owner and get more details about who is hunting their and when. Maybe he will know. Also ask what his policy is in reserving spots. If it's public land then that's another matter. Public land is for all to use and noone should be reserving their spot. It should be "first come-first served". But you'll more than likely catch a bunch of flack from these "land hogs" if you're set up too close. I think I'd just as soon find another place to hunt. Sounds like there's too much scent floating in the wind anyway.
