Funspot, and all the Weirs Beach arcades, are reasonably close to Plymouth.
Super-old coin-ops, mainly for viewing rather than playing, are part of the attraction at Clark's Trading Post in North Woodstock.
Thanks KozMck for the report on the Omni Mount Washington. Anyone have any sightings in the Littleton/Saint Johnsbury region?
As for Canobie Lake, see the thread where I reported on my trip last year.
