There might be a parking issue at Robbins Pond. I just remembered all this drama.

I don't what's happened since then, but parking there might be more hassle than its worth. Parking at the bog pond above Robbins might be a better idea (it's a better pond, too, but you could allow people to fish both; or all three since there is a second bog pond back there), especially if we get permission.
You can't get close to the water at it several timeshe upper pond at Robbins. Access has been gated off for awhile now. As far as Furnace goes, about 6 cars can park at the beach area at the south end off of Furnace Colony. Big dredging operation is supposed to get underway in the spring!
