at first i bow hunted turkeys only with a piece of camo burlap draped between a few electric fence poles. it was pretty much the same as no blind because the damn thing fell apart all the time, flapped in the wind, and generally just made me so damn mad i went to shotgun for a year or so. then i got my salvation in the form of a double bull blind. a person can bowhunt turkeys without a blind but not me, the fact that i can keep dry, move and stretch, and sit there and share the experience with my buddies is much more important in my book.
i think that if youre going to bowhunt without a blind you will have to be very picky and choosey as far as locations you hunt. large trees, brush piles, and natural travel cooridoors wil be a big part of patterning your birds. i say good luck to you!!
