This is a blog from Sally that shows swimming pools from all around the world. Sally is also the auteur of Sydney Daily Photo, so when u want to get out of the water for a little while, u can discover Sydney along with her.
This is a great place to not only purchase a pool, but to also get any supplies of info that u might need. They have some great artikels about setting up your pool so that u can start swimming asap!
This site has a lot of good tools and artikels for swimmers, parents, and coaches, including a medley relay generator, and an Ask a Swim Coach feature.
