He probably payed someone to lease the area. I have heard of this happening more than once.
TFOX, might be on to something. I can see the scam now. Guy asking around last minute
to lease hunting property. Some grifter pulls out a township map, outlines the area and negotiates
a "sweet deal" for our dupe. That is really not that far fetched. That also wouldn't make the
scamee think much of the posted signs. It's a good scam for a sucker who doesn't bother to
check out the guy or the property first.
