Biking to Great Camp Santanoni

I just heard a report on North Country Public Radio (NCPR.ORG) by Brian Mann on his bike trip from Newcomb to the restored Great Camp Santanoni. I didn't know that that was allowed there. Are there any similar old roads accessible to bikes (but not to motor vehicles)? It appears that DEC management regulation don't have that catagory. Another road which might qualify is the road to Boreas Pond, where biking is not allowed right now. None of the proposals seem to include biking without motor vehicles.
