There was an estate auction here last year that was kind of like that, but just bikes. The outside bikes (like the ones in this sale) were mostly scraped, but he had dozens and dozens of bikes in a warehouse (yes, a warehouse in an industrial area). They were mostly 1960s and 1970s and not especially noteworthy- Schwinns, Western Flyers, etc. I didn't see any quality Euro or Asian bikes in there, so I passed.
