Dear K.,
I don't personally have a pool, but I know many people who do have them.
For one thing, we live in earthquake country. Cement pools or fish ponds crack and are a huge pain in the rump to try to repair.
At least in our area, fiberglass is much more forgiving.
In ground pools are awesome either way. I wish I had one. But, you have to make sure to have safety latches on gates and fences and a way to keep children from just hopping in or falling in by accident.
My friends live where it's in the hundreds right now. But, in the winter, it will snow. They got a huge soft sided above ground pool with a pump and sweeper, the whole thing. It's up in summer and fall, put away in the winter. Aside from the time it takes to fill it with water, it only takes 45 minutes to set up. They've done it for years and have their system down.
Whatever you get, just have a great time. My dream is to have an indoor/outdoor pool so we can swim year 'round.
