Peace and quiet seem like good things until you’ve had too much. Keith Davison got his fill in the months that followed the death of his wife Evy after 66 years of marriage. But it’s not quiet at Davison’s house anymore. Late this spring the 94-year-old retired judge installed in his backyard an in-ground pool – then filled it with the neighborhood kids. Davison’s backyard addition is no mere wading pool, at 32 feet long – and 9 feet deep under the diving board. It’s a welcome addition in a town that doesn’t have an outdoor public pool.
