Well, it might not be squirrel damage, but we're not sure we can explain what the problem is otherwise. Our previously functioning solar power heating for the pool has sprung a leak - a big leak, in fact. The new pool maintenance service sent me an email saying that they'd put the solar on, then turned it off as "water was pouring off the roof". They said we'd need a new panel to replace one that was damaged.
We are always skeptical when things suddenly go wrong. So we turned on the solar and, darn it, water poured off the roof. Here's a photo of Deep Thought experiencing our impromptu roof shower.
This didn't stop us having friends over for lunch on Sunday. Seven children and one brave adult went swimming in our low-80sF water. Reports are good, though Deep Thought said she couldn't really tell that the plaster was much smoother than the old kind. However, since none of the kids got out with "raspberries" on the bottom of their toes, I guess this was a successful experiment.
