Rust Valley Restorers held a successful and “bittersweet” auction this weekend that emptied out his famed “field of dreams” in Tappen, B.C.That’s where more than 550 of his classic cars in various states of disrepair have been parked for decades, awaiting restoration to their former glory — a process that famously plays out on the show.By the time the weekend came to an end, all but 50 had been sold to the highest bidder.“I kept as much as I could,” Hall said, noting that some of the cars he’s had for as long as 40 years, while others have too much potential to part with.The rest, however, will be towed out of sight before the snow flies.
