RE: public land with stands
Here in Michigan you can put up a treestand and leave it there for the season as long as youdon't attach it with nails or other means that would destroy the tree.
You also have to have it clearly mark with your name , address and license number , by the end of the season you must remove it.
If you happen to put your stand on public and state land where they allow hunting and somebody elsehappensto be init when you get there , you can inform him or her that it's your stand but you can't make them get out of it.
