I do in nearly all the places in central OH I hunt. Not so much in southern OH/Wayne Nat'l Forest. Back in PA where I'm from, I could get 1 bar most times from the parking area, hardly anywhere I was hunting on the ground, but good signal from my brother's treestand on the ridge.
I used to refuse to carry one in the woods, but after my son spent an extended stay in the hospital, I kept the tether attached. Took awhile to train the wife about what constituted a valid reason to call, and that texting is the same thing as calling me when I'm in the woods!
