"Ran when parked" is one of those classic things you read in old car want ads, usually for some old crock that's been sitting under a tarp in someone's back yard for 27 years. It almost always means "won't run now", along with "brakes seized solid" and "squirrels have been storing acorns in the exhaust system".
Anyway, I thought of that phrase when I found this old Schwinn parked in front of one of the warehouses at the former Green River ordnance factory. It looked in pretty good shape, but it had certainly been sitting a while. The headlight was rusty, the chrome peeling, the tires flat.
