The house we bought (about a year and a half ago) came with a pool and a hot tub in the back yard. Calm down...it's not as good as it sounds. The pool is horrible, above ground and a pain to keep up! The hot tub, on the other hand is pretty great! We use it most in the fall and winter (almost every night). Nothing beats a nighttime visit to the hot tub on a crisp fall night or on a snowy winter night (yes, it is too cool to be in the hot tub with snow falling).
Anyway, we got a new filter and fresh water and we are back in action. It is on tonight!
