Update: We just returned from the auction preview at Sunset Bowl, and the parking lot is already packed. The auction (details) is expected to last well into the afternoon, with some of the more interesting items (bowling pins, for example) scheduled to come up around noon or later.
Notice that the bowling pins come in large lots. Same for the bowling balls.
The computer displays, monitors and blue chairs are for sale, too.
Even the lanes and gutters are up for auction.
The best pick that I could see: this cool Sunset Bowl welcome rug, which will almost certainly draw a high bid.
