I have done a lot of hunting out of blinds and some spot and stalk hunting. Where I hunt, there is a lot of brush around the waterholes and the antelope are scared to come close. I don't think the blind scares them much but that the tall grass does. Using a decoy to give them confidence that it is safe to come to water seemed to make a big difference. Also, when antelope come to water and then run away, don't worry that they smelled you and spooked. Usually, they are testing to see if the waterhole is safe, and they will come back after they run off. It is probably different if there is no a bunch of brush around the water. Another point -- practice a lot out of the blind. It looks a lot different and without practicing it, it is hard for instinctive shooting. pc
