Peter, I'm not close enough to see this show, but I have alerted my brother who lives within driving distance.
The location of this car show is unclear to me, "East Lawn OVP Settlers Green " is what shows in the notice.
Is that in downtown N. Conway, at the Mt Washington Hotel, or at a secret location known only to locals ?
2 years ago I happened on a local car show organized by the White Mountain Cruisers (Littelton, NH ) in Bath NH.
Bath has a covered bridge and the oldest (claimed ) general store in the U.S. More pics of the cars later.
I will be in VT & NH in early October, stops will include the Fryburg Fair and the Maine coast.
