Porsches to Ohio (aka P2O) is an event that is coming to Granville late in July. Do a search for the details (there are a number of sites detailing the event and past history when the Porsches were gathered in Oxford Ohio).
Personally, I prefer the 914-only ambiance over some of the arrogance associated with owners of the late model, high tech, megabuck, high horsepower Porsches.
I registered for a P2O gathering a couple years ago and the organizers rankled me so badly
that I swear I'll never attend that event. (It had nothing to do about 914 ownership, however).
Headquarters for a 914 gathering.....Dublin? Delaware? Lancaster? A state park with a nice lodge or inn?
