On the State ground I hunt, you can put up 1 stand that has to be marked with your name, address and phone number. It can be left for the entire season and by site rules it is to be removed by Jan. 31. I was just up there scouting on the 3rd of Feb. and counted 5 stands still in the woods and believe I could find many more. Personally, I would never hunt from anyone else's stand, regardless of how long it has been there. To each his own.
