just came across a Westchester cycling map last night. I'll take a look at it tonight to see if there's something good to share. I think I remember researching vast long paved bike trails but never got to test them. I think they still close the Bronx River pkwy on Sundays and that's a fun big social event and especially fun to ride on a parkway. have you narrowed down your approx landing spot? meaning a town or two near where you plan to stay?
