I've never hunted from a pop up blind, but I do have some brush blinds here and there in good spots.
I usually start my day in one or the other, but if I have a bird gobbling at me that won't come in, I go after him, and use what natural cover I can find to call from.
It's become my favorite way to hunt them, and I've killed some birds doing it over the years, but there have been lots of times that I've either been busted, or couldn't draw my bow when I had a shot, because I would have been.
However things turns out, It's a heck of a lot of fun, and rewarding when it all comes together.
