You know you've been filling sandbags all day when you start getting picky over the kind of bio-degradeable bag's you're given. There are flavours from China, Indonesia and India (at least). I'm biased towards the Chinese version which require a separate twist tie.
The only skills required for sandbagging are digging and counting to two. Even YATS can handle that. Once filled the bags are taken to suspect levee locations which have been given names, eg Dead Dog, Pole, Horseshoe, Miller's Corner. I'm trying to find someone who can tell me if we're presently winning or losing the war. More rains north of us expected - not good news.
