An embarrassment of debris riches

What are these things? They look like springs. They're steel (magnetic), their ends are sharp, and they were strewn in the bike path on Dexter. I picked up all I could find, but I'm sure I missed some.

I'm pretty sure they're the remains of tire chains. People in Seattle get only sporadic practice in snow and ice, but sometimes it's very slippery and Seattle is a hilly town. So people put on tire chains, but because they don't get practice, they buy lousy tire chains and put them on wrong. The result? Shredded tire chains make a wreck of the paint on a quarter panel, before spilling their guts on the roadway. Since the City takes a mild interest at best in street cleaning, late winter Seattle streets are a debris field of tire chain guts. Cars run over them until they end up where? In the bike lane.

So I and every Seattle biker gets to dodge bits of what look like purpose-built malice because why? Two reasons:
- Lousy tire chains that ought not be legal to sell.
- A city that cleans the streets approximately never, despite the fact that it would make the city money to clean.

Grrrr.
