Driving up to Mont then coming back down. 4 people, 3 bikes, 3 days, 1 car, 2 tents, loads of food. Having scanned a couple of topo maps I'm thinking of heading for Lake Champlain and scooting down the Western shore and aiming to drop in to the Hudson valley where it swings South. The rest is straight forward except for camp locations.
Hopefully someone has ridden between to two cities before and can offer some exciting deviations/hills.
