Welcome to our forum.
I like the chance to get away for minutes or so and just unwind. I really take advantage of the personal therapy side of things and its great when my soon to be wife joins me.....but being alone in the spa I also find to be very relaxing and away to get away for few minutes....
I've always had a real fondness for the therapy a hottub provides. Before owning one, I was always sneaking into apartment complexes near my old house and using their tubs.
