OK, so I've been picking out at least 8 potential ground blinds for the suburban bowhunt, which occurs in two town parks, both of which contain hiking and biking trails for humans. These parks are 240 and 160 acres each. I try to get as far from the human trails as possible. Two season ago, got my first buck, and later realized that I was hunting only 20 paces parallel to a human hiking trail(I think the deer thought the last human had just gone home!) Whenever I have visited this off season, I've tried to separate my visit to any one blind by at least a month or two. Now that we only have about 6 weeks until the opener, any advice on how often to visit blinds for some last minute brushing-in or shooting land prep? Obviously, the deer are used to hearing, seeing, and smelling people, but hopefully not too often at my off-trail ambush sites.
