I agree, contact the landowner. I know around here it seems like half the landowners will say take the stands down (don't take them either way) and the other half say they may not have permission, but the LO doesn't care. Whatever you decide to do... Think first about how it will affect yourself and other legitemant hunters. Don't do anything that will close off another private land. Many of us know any kind of fued -no matter who is "right" -will sour a private land owner, and discourage them from ever letting anybody hunt on there property again. ALWAYS respect (contact in this case) the land owner FIRST!!! PLEASE!
