If your looking for a last minute Mon. trip, We're going up the Ammonoosuc Ravine Tr. So........ be at the Cog area 8:30. I'll still check this thread later if you have any ?'s.
We did go yesterday. It was, (lost for words to describe it), GREAT! How's that? We parked up at the Cog (Marshfield Station, the original trailhead). Park off to the right. I've heard all kinds of stories re: parking??? Just be courteous & quiet and go about your business.
