In general, I vastly prefer friends with a pool to owning one of my own... kinda like boats, ATVs, jet skis, etc....
I had a small above-ground pool last summer and got lots of great use out of it for very little $$$, but was ultimately too busy to do a good job of cleaning and care, so DW grounded me from pool ownership and we junked the nasty green remnants in the fall (I was sad but didn't fight it, as much as I love pools and hate waste, because she was right... I couldn't hack it with my schedule like it was/is). Maybe post-FIRE, we'll revisit this topic.
