For those in the Minnesota/Iowa/Wisconsin area Classic Motorbooks in Osceola Wisconsin (about 1 hour NE of Minneapolis) is having their annual Wings and Wheels event on September 8. For those of you not familiar Classic Motorbooks is a huge Internet/Catalog bookseller specializing in books on mechanical subjects, particularly military, automotive, motorcycles, trains, aircraft, etc. Each year during the town fair they open up the warehouse (you can literally browse every title on every shelf) for an inventory-wide sale and stage a classic car show that usually hosts around 1,000 entries. They have a sliding scale of discount depending on how much you buy and a "scratch and dent" tent set up outside where individual titles are up to 50% off.

They carry all of the Osprey titles - take up an entire wall in the warehouse. Not enough hours in the day really to peruse them all.
