Inspired by the strangest thing you've carried.
A few weeks ago I was near an airport and for about a quarter mile of road, around a corner and on another 1/8th of a mile I saw what looked like red co2 cartridges all over the shoulder. Hundreds of them. This is out in farm country.
I kind of wish I picked one up. No idea what they were, but they were so bright red... Crazy.
