This is my experience. I'm in Southern WV, Flat Top if you'd like to know the town, I live very close to a Ski Resort, and lots of other Rec land around. I practice "right to roam" I don't have a single no trespassing sign anywhere. But, I do have other signs. Please Close Gate, Nature Sanctuary, etc. When I see folks I normally chat with them, tell them about the amazing view and and polite instruct them of some of my requests. I added Trash Can in a few spot (Normally where the ski/snowboarded jumped the fence to "hangout") At one point a lot of kids started milling about, so I install a 9 hole disc golf course "free to play". When young adults would try to use the top of the mountain for a red neck breeding grounds, I was drive up there and play 70's porn music, but never interaction with them. I wave a lot, I let people metal detect, and general treat them with kindness. Most of the "bad" people go away, and even a few of the teenager, turned into adults later came back to talk to me to ask why I cool? -- We have no "law" here Southern WV is pretty much free, (we also all do own guns, and WV is extremely gun friendly) What I found is most people are cool, they just want someplace to go to get away from what ever real life issue they are running from.
The handful of "bad" people were dealt with pretty easily (I grew up in the inner city of NE Ohio, a little street smarts make you magic in the country)
a.) We had some kids cutting my cattle fence, the cows got out, we closed the main road (folks trying to help me get the cows back in) story got back to the family that the reason the main drag was closed was because some punk kids were cutting cattle fences and magically the fences never got cut again.
b.) I added more gates on the road up the mountain in completely pointless areas and the drunks stop driving up there.
c.) I got guineas
d.) Posted a letter at the post office about the request I have if you want to free roam my land.
e.) and just invited more people to hike, play, fish and whatnot.
Killem' with Kindness. ( PS for legal advice I tell everyone to play at your own risk, I know not the dangerous of my land)
