The strong wind pushes my empty sardine can around while I eat lunch outside Kelso Depot
I'm eating two cans of sardines for lunch. I hold the empty first can while I devour the contents of the second one, to keep the wind from blowing it away and splattering me with stinky fish juice.
I carry tinned sardines on most of my trips because they don't require cooking and thus provide an excellent emergency high-protein meal should my propane burner run out of gas or malfunction.
However, I rarely eat them unless I'm near a trash bin, and I often end up bringing them back home with me. They make for stinky, leaky garbage that one doesn't want to be carrying around a few days until reaching the next trash bin!
