I have a battery charger which I bought because I got tired of buying batteries for my digital camera which is really hard on batteries. We were in Washington, D. C. a couple of years ago and even though I had put in new batteries before we left that morning, right in the Smithsonian, probably taking a picture of Archie Bunker’s chair or Elvis’s guitar or something, my camera died. So that was that, and we were scurrying around the shops in Union Station looking for batteries, which, when we did find some, cost a fortune; I got the tourist rate! I thought, there’s got to be a better way. So I got this battery charger which allows me to use the same batteries over and over and I always have a fresh set ready to go. Now if I can just figure out where my brain goes or my heart goes or my aching back goes, we’ll be just fine.
