I hunt open territory where it's just the hunter vs the game. But if I were to use any style of concealment I'd choose the blind. Tree stands require a lot of calculations for the angle of the shot, which can vary dramatically in a tree stand, and tree stands offer a whole new level of hunter safety issues that I don't want to deal with. Feeders aren't legal in this state (and I don't believe they're an ethical hunting practice - it's called "hunting" for a reason.) so I can't address that issue from the point of experience.
blinds or treestands ?
