I've been using popups' for about 5 years now. Deer seem to notice ANYTHING that is different. It dosen't seem to alarm them unless they have smell on them, (as ALL new blinds do) I set mine up in the yard wash with a good no-scent soap and spray with UV killer. If I can I always brush them in, however I have found that just settin' it up, deer will accept it in about 3-4 days, if the deer use the area daily. I alwys keep the mesh up with NO windows or light behind me. Deer willnot accept a "blackhole" in the open or brushed in. I have lots of deer, I get deer within 10 feet of my brushed in blind almost daily. It's been up since mid SEPT. Turkey's don't seen to mind it set in the open or the "blackhole" Mybe I'll get around to posting a pic of my brushed in blind. Good Luck. I think you will enjoy hunting from a blind, but....they do take some getting used to, so don't try it 1-2 times and give up!!!!
