well sadly I hate to say it, but if its not your land, you have NO right to tll them how or why they can hunt there
that privlage comes from owning the land, or working with the land owner
something you might try, however is,,maybe contacting the bank that own's it, and asking them for written permission, and possible
authority to throw out trespassers, and or call warden on them
making you the soul hunter on it
this way your legal, and can even offer to post it for the bank , thus maybe keeping more folks out
and showing others where the boundary lines are
and then have a place to call your hunting spot
Other wise, if your trespassing(if you don't own it or have written permission, that's what your doing)
and then your as guilty as everyone else that is using this land
I know that doesn't sit well with folks that grew up using lands, and as such tend to feel they have rights to them(big issue up my way)
but that's what happens, people FEEL they used to, so its now a right of there's
regardless of what the owner thinks, as there the one's paying for the lands, so many use for free and get bent out of shape when other use it as they do!
its a pet peeve of mine , due to all the folks I get on where I hunt that think cause 30 yrs ago they had access they still should, get in many heated debates on trespassers I catch every yr due to it!
when folks start paying for the taxes, and the land in general
its THEN they have the right to tell folks how they can or cannot hunt it
till then, your, wasting time and breaking the law!
but again, call that back and try, never know what door you can open, as banks tend to own a LOT of land, might get you more access to better grounds working with the bank!
