One day on the way home from work it started to downpour. I pulled off the side of the road and put on my rain suit. No big deal, just a little rain (and thunder, and lightening, and flooding). So, when I'm a little more than halfway between where I stopped and home, I noticed that I had forgotten to zip my bag back up (Nelson Rigg soft bags). I had to backtrack through the storm and pick up items as I found them... the last one being about 100 feet from where I had stopped.
Sometimes it sucks to be me. I haven't done it again... yet.
