with the exception of finding a good oak with pines next to to hide me I I am at the least 25ft I have one at 16 but it has 4 thick hemlocks around it so you can't even see me, but thats the exception to the rule. I personally like to find tree's that are surrpounded by thick pines to me I feeel as though I am less likely to be spoted especially one all the leaves are down those are the only places I put a stand, but thast just myy tactic
