Sunday Yard Sale at the Flea Market Wife and I are hoping to get rid of some our things this coming Sunday (Oct 4th) at the Williams Grove flea market at 1568 Williams Grove Road, Mechanicsburg, Pa. Plan on starting to set up setting up by 6am if possible. We will blue and white balloons at our site. See the many pics. Some, but definitely not all things we'll have is ... Some sterling pcs, vintage models (never put together), some 60's matchbox, a few other old cars, some vintage albums, some ps4 games, old kay guitar as-is, rare 1996 Egyptian Playmobil pyramid with a lot of accessories, tote full of vintage Star War/Yoda pcs... And more. Please bring small bills if coming early.
