Where to after the Tappan Zee/MCB? Planning a ride over the new bridge on Monday, starting from the Nyack side. Am I making a left on the other side and heading into Tarrytown to catch the North County Trail or is there another way I should consider? I'm expecting it to be a light day, 25-30 miles round trip. 
We've done the South County trail from Van Cortland Park to Elmsford but that's all I know about the area.
Any advice is appreciated!
