Mac - I teach Hunter Education
1. Get yourself a 5 point safety harness. I know all the big tree stand manufacturers include a 5 point harness when you purchase a stand. But I highly recommend the Hunter Safety vests. Which ever you choose. They are far easier to use, far more comfortable, gives you a few more extra pockets and are built to save your life. It is all they sell as they are not Tree Stand manufacturers. BUT RELIGIOUSLY wear it! Never Leave the ground without it. 85% of all hunting accidents is because of tree stands according to the data presented at our Hunter Ed Instructor meetings.
What I wear either over my clothing or under my Blaze orange coat. It's my second skin when I leave the ground.
2. I m certain cutting of any live limb on any said tree in any national forest is against the law. So do be careful there to. The fines are steep. In all the County, State, and National Forests in WI it is illegal to screw anything into a tree or cut any limb. So do check.
