I am using one now for deer hunting. And will use it for varmints. I got the cheapest one, a tee pee for about $30. I have one of those folding lawn chairs. very comfortable. keep the wind out. and if you are comfortable you will stay longer. I bought 2 and go to different sights, pop it up and am in business in 2min.
and I am confident that it hides scent. I had the biggest bobcat I have ever seen leisurly walk withing about 15yd of me and never look my way, along with other assorted critters.
where I live in NE kansas I hunt wooded draws, creekbottoms. I need a orange tape to find it. It looks like a briar tangle from a distance.
I do not like tree stands. they are cold and most of all dangerous. A local guy here is paralized from falling, and I have heard it is not uncommon. Now when I was younger climbing trees was better. the blind is a good option.
