I will chime in with my .02, you can keep the change...
I put a commercial blind up this fall. I placed it up against a tree and scrub brush, thought it was kind of hidden in plain sight. I also brushed it in some but the greenery died so I don't think that helped as much as I thought it would.
I placed the blind about 2 weeks prior to our seasoning opening also. I left one window open hoping the deer would get used to seeing the "black hole".
I saw deer, they came out into the field about 75 yrds. from my blind. Came out right where I thought they would. They made it to about 30 yds. and looked my way the whole time. Very cagey and on edge.
They wouldn't commit to coming any closer. In fact, the yearlings got what sounded to me like a tongue lashing from mom as they were coming closer. They turned and ran back to her.
I have since moved the blind, BRUSHED it in and closed the netting on the windows. I'm planning on hunting it this week, we'll see if there's any difference in their behavior.
Good luck and let us know how it works for you. Oh, and for what's it worth I am using the ASAT blind as well.
