I'm spoiled here in Az...I don't have to deal with the frigid cold...only had a handful of days that were below freezing this winter...I get 14-15 dollar average on a 500 gallon HS Grandee...And I don't have to make a mad dash to and from the Hot Tub!!! Not sure if I would survive in a really cold climate with a hot tub! Who's a sissy.....This guy!!!!
