Since we have a swimming pool at our apartment complex, I like to go swimming often. However, I know many homeowners who have their own Shasta Pools that allow them to go swimming in their backyard without having to share it with anyone else.
The Shasta Pools company started in 1966 and has since expanded to have a large user base in Arizona (they are currently the number 1 pool builder there). I totally understand why so many people have Shasta Pools installed in their backyards-- the weather can get almost intolerably hot there and a pool would be a great relief.
