Where does the Old Croton Aquaduct start? Where does it end? How does it get from there to here? Come with us and see. We'll train from GCT( 7:25 AM)or 125th St.(7:40 AM) to Croton on Hudson, climb to the dam and follow the Aquaduct from there. There are gaps. But, the leaders will fill them in. The terrain ranges from pavement, hard pack to a little primative. Lunch probably in Tarrytown. Bring money for lunch and train fare(and your Bike Pass). It's an adventure! Are you up for it?
