Just like in SD, here in Iowa 15 to 20 MPH is the norm and I don't have many trees big enough for a stand. So I do 90% of my hunting from the ground. I do have 1 permanant stand built in a tree, about 20 feet up. But it's uphill in front of my stand so much though that a deer at 40 yards is almost eye level. I won't go in the stand if it's real windy like yesterday. That costs me a shot at a real nice 8 point but I would rather have him scent me at 60 yards then fall out of a tree. Guess I'm a chicken.
