UPDATE: As Bill notes, there’s also a May swap meet. That should not be confused with the August Annual show.
This August the National Pike Steam, Gas & Horse Association will be holding it’s annual show in Brownsville, Pennsylvania. This year it will be featuring working jeeps. Learn more about this event at http://www.nationalpike.com.
Had to look up Brownsville, PA
About a 1/2 hour south of Pittsburgh. Just below California PA.
Just to clarify, the jeeps are needed for the August show. May is their flea market.
