I recently purchased a Lone Wolf Alpha Sit and Climb Treestand. I've used it twice while hunting here in New Jersey during the January permit season. The air temperatures have been brutal cold during the two hunts that I used it. The cams that hold the adjustable strap in place are impossible to open with your hands. Anybody else have this problem? Other than that, I've had no other problem with the treestand. Any way to fix this problem? Loosing the bolt that holds the cam in place will not help. I've done this. Thanks in advance for any input.
