A lane-walk meetup is exactly what it sounds like: a handful of buyers meet at a public-preview yard the day before the sale and walk the rows together. Four sets of eyes catch what one misses — frame kinks, mismatched panel gaps, flood silt in the spare well.
Etiquette that keeps these useful: share observations freely, keep your max bids to yourself, and never touch a lot another walker is photographing. Post your city below if you want to be pinged for the next one; most yards allow preview access with a simple registration.
