Yesterday, while killing some time before heading to the theater to see Oz The Great and Powerful, the Nerd Cave Family pulled into the local antique mall. You probably have at least one in your town. The massive steel building crammed from floor to ceiling with junk, treasures, and everything in between. Like most, this particular store is made up of dozens (if not hundreds) of booths belonging to dealers of everything under the sun. If you’ve ever been to one, you know that one person’s definition of “antique” or “collectable” is often much different from yours.
