About 5 years ago I found a little pile of my dad's old tree stands. Home made but extremely well-engineered.
He had parts to make more so I did. Tried marketing them. When I discovered that the "pokey" part of the stand was illegal in some states that ended my deer stand enterprize...or did it?
Re-purposed them as a way to position a bee box on a tree to trap warms of bees. There is an attractant called "swarm commander" that mimmicks queen pheromone and the stuff really works. At $150/swarm I'm making more catching bees than I could ever have made selling them deer stands.
Caught me another one today. Beats the hell out of climbing way up on an extension ladder.
