They're rare up here but exist. I have two friends who have pools. One is off Desert Front and the other is on Easter Dr. They have had them for years and use them often. So yes, it's possible. 
Awesome! You don't know if they would be willing to talk to a stranger about what they have to do for pool care in the winter do you?
I'm not too far from Easter, so it would be a huge help to be able to talk to them.
Thanks!
