At the very latest a I have everything set to go a month before the season but try to have most set by Memorial Day. Not only to give the deer plenty of time to adjust but to avoid the heat and bugs when putting them up. We also try and do any major trimming then. I'll have a couple more going up here next week and check all other stands for any problems and do any minor shooting lane trimming. Any major trimming for new stands I like to have done months in advance, deer don't recognize the little stuff as much as the major stuff.
