Das Awkscht Fescht is a 3 day car show / automotive flea market in Macungie, PA (near Allentown, PA) during the first week of August (Aug 5,6,7 2011). It is one of the best and nicest car shows in the Northeast US (although it is usually very hot). Discounted Pre-Registration for the car shows end December 31 ($10 per car per day). Pre-Registration for the car shows end on July 1,2011 ($13 per car per day). No at gate registration for the car shows. The fleamarket is best on Friday and Saturday. Car shows are best on Saturday and Sunday. I think up to 1986 cars are allowed this year.
