A few years ago I set up a pop-up blind on a field edge late one afternoon, and the next day I had a buck repeatedly chase a few does within about 30 yards. What really took the cake was when that buck came within a few yards as I was packing up to leave. I could smell him, he was so close. He didn't pay me any attention whatsoever since he was hot on the trail of another doe.
You definitely want to set your blind up within some cover and brush it in to further conceal it. If your blind has mesh velcroed in the windows, take it out even before the hunt.
