A link at SNAFU's place showed me a fast, ingenious way to fill sandbags.
When I think of the literally thousands of never-to-be-sufficiently-damned sandbags that I filled the hard way, bending over with an entrenching tool and scooping sand, earth, mud and rock into a bag that always flopped closed at the critical moment . . . I'm speechless with a combination of rage, envy and bitterness. Why didn't we think of such an ingenious device when we needed it? (On the other hand, if we had, I'm not sure our NCO's would have let us use it. The old-fashioned way would probably have been considered "character-building", or something like that - and besides, there are no PVC drainage pipes on the average battlefield.)
Be that as it may, this method can be really handy for flood preparation. I'm sure many of my readers have seen news reports, like the one below, showing armies of volunteers filling sandbags to protect buildings and vulnerable areas from flooding.
I hope civil defense authorities take note of this improvement in filling technique, and have a number of those devices standing by in case of future need. They're so quick and easy to make, it would be stupid not to do so.
Nevertheless, my back is still aching with the memories of the old-fashioned way of doing things . . .
