as many as you can. Unless your in an area you could have it tampered with, them suggest taking it with you when you hunt.

As soon as you can like stated in the post above...I put mine out 1 week ago and today I seen deer all around it so it must have been out long enough lol.I brushed it in pretty good with tree branches/leaves though...
my ground blind and tree stands have been in for a month now. Deer are used to seeing it by now, just hope there still there. Will be really ticked on opening day if there gone.
