Up on Monday and back tonight, and not a Vanagon to be seen.  Did see one Bay camper on our arrival and saw two curious EVs.  One looked like a silver T5 which, by the stance, could have been a Syncro.  Bikes on a rear rack, it was heading sound on I-81 near Harrisburg.  Then, yesterday in the parking lot of the visitor center at the Gettysburg NHP I saw and got pix of a T4 with Austrian placard and plates, a Syncro rear badge and front sticker, non-Westfalia poptop, F45 awning, 5-speed and probably a diesel powerplant. It also had a Paulchen-type rear rack with a Rola-type plastic box for additional storage. It was a real treat to see it and I hope the owners are enjoying their U.S. visit.
