Geez, Leno, Leno LENO!!!! Be CAREFUL will ya??

Had a similar accident on my bike. Heading to a hardware store next to a drive-in theater with a swap meet. I didn't know the hardware store was closed. They had strung a cable across their driveway to keep swap meet customers from parking in their lot. And there was a lot of loose sand on the street in front.
When I saw the chain, I jumped on the brakes, and lost it in the sand. No chain, the sand is no problem, no sand and I stop short of the chain. No injuries beside a scrape or two, for me or the bike. (But I wasn't 72 at the time, either).
I honestly don't remember if the chain was marked, but I don't think so. Nowadays, sounds like an automatic lawsuit.
