This reminds me of living in Carlsbad NM back in 1961. Everyone had to lock up their bikes due to thefts.
In 1971, I visited Santa Fe NM. There on the SE corner of the square was a large parking lot with a light pole. Around that light pole was a chained up bicycle frame. NO wheels, handle bars, chains or pedals. Just a frame.
I have seen that happen in Seattle, where a well secured bike just loses parts over a period of time, until nothing of value is left to be stripped.
