Cooler weather is just great. Now if we could only get the weather to cooperate and at least cool off at night for soaking. Went in the past 2 nights and it felt just heavenly. I didn't think I'd miss not going in for a few months because of the heat, but I really did. It gets addicting. We live in northeast Pa. and it has been so hot for so long that I noticed that the heater did not go on for days, it just stayed hot. And the tub in not even in the sun, it's on the patio with a roof over top. I have it set at 98 for now.
