He' s probably just worried about you falling out of it and suing him. Many land owners I' ve talked to all know someone who knows someone who' d been sued by someone who fell out of a tree stand. In the past I used to offer to sign a waiver releasing them from responsibility .. and this year I had my first person tell me that wasn' t good enough .. this land owner knew someone who knew someone who was sued because someone fell out of a stand on their land and they even had a signed waiver. The person who sued the land owner was the person' s wife who wanted to be compensated because her husband was missing work!
