Hi, Barb. Dook locks, special keys, garage door openers – oh, my! 🙂 I'm reminded of my childhood in the Bronx. My mom and dad were super-security conscious. Back then (in the Cenozoic?) we didn't have any such sophisticated lock-up devices. My mom and dad had a series of bolt locks on our door. Every night I'd hear the clack, clunk, ka-chink, click as they went through locking the locks, one by one. I was spoiled by moving out here, to a quiet mountain town. At first, it was a surprise to see how neighbors went about: leaving their bicycles and/or x-country skis propped up outside of shops, unlocked, just standing there; and to learn that at home hardly anyone locked their front doors. Even though I now live in a metropolitan area, I still often go off on errands, forgetting to lock my front door. It's a leftover forgetfulness of living in a sleepy mountain town. 🙂 –Ray
