Each spring and fall at the Jefferson County Fairgrounds, at 15200 West 6th Avenue in Golden, the Jefferson County Library Foundation stages a "Whale" sale at which books, magazines, records and more that are being taken out of circulation are put on sale to the general public. The four-day event begins with a preview night on a Thursday, a $10 early-entry opportunity for an hour on Friday morning, and no-fee entries through the rest of the weekend. But the real bargains can be had on Sundays, when patrons are charged just $6 to fill a grocery-sized bag with as many items as possible. Fees are bumped up slightly for larger bags, but it's still possible to pick up dozens of books for a quarter or less apiece. A whale of a sale, indeed.
