If it's private land and you are not worried about the blind coming up missing I would put it up and leave it up. You will hear many say that you can just pop up a blind and hunt turkeys but any smart birds may figure out that something is amiss. It isn't easy setting one up quietly in the early morning the day of a hunt anyways. Field edges are best, backing it up against a thicket is good. If you are setting it in the woods then keep in mind turkeys like to be able to see distances so the more open woods the better IMO. If you have time to sit somewhere and listen in the evenings you may be able to figure out common roosting sites by hearing them fly up to roost.
