I was at the Amherst/Springfield train show and wasn't expecting to see slot cars so this booth stopped me dead in my tracks. "Model Train & Slot Car Shop" Michael Shipp 891 US Rt.1 York, ME 03909, 207-363-4830 and he is on facebook. He had large collection of early mid 70's HO cars some Ninco classics, Fly cars etc. He was super nice to talk to and I wish I had taken a photo of his display as I can't remember half the cool stuff he had.
There seems to be a really good group of North-East guys here and any new shop opening is rare these days.
