Glad the have you back posting with us. I am not quite familiar with your fall and spring temps in North Georgia. But here in Southern Maryland they can get down to the low thirties to mid twenties at times. In those conditions I use my Speer Winter Tarp pitched with the sides low to the ground and with the end flaps staked in. Which creates a almost tent like set up. I use a tyvek ground cloth under my hammock. When my dog comes with me. I carry a small fleece throw blanket. That I put on the tyvek and she burrows into and curls up in that and seems to do just fine. She likes the fact that she is close to me. I never tried putting a tent up for. But I do not think that she would like being away from me anyhow and I would not like to have to carry the extra weight.
