Yup, for a while anyways. Back into the 70's for a bit again now though.
I've gotten in the pool once thus far since putting it up right before Memorial Day. 3 days of 90° or near 90° with no water, then 2 weeks of 60's and 70's with full water. Water temp too cold this past Saturday but finally tolerable on Sunday. Back to 70's now.
A ton of rain a couple weeks back had me pumping out a few times. Three inches in one afternoon downpour had the level above the top of the skimmer. The kids don't care what the temp of the water is, they would jump in if it was 70 degrees. SWMBO and I like it in the mid 80's.
It's a simple vinyl post/rail with the safety mesh attached to the outside. I'd rather it looks good on the side that I see than the side everyone else sees. We love the farm fence look. I bought some cheap ($1 a piece!) solar walkway lights at Wallyworld, detached the lights from their little spikes, and attached them to the top of every other post...it looks great at night.
