Westchester is a large county....IF you were at the Tappan Zee Bridge (Tarrytown), you'd be 40 minutes away. IF you were at the Bear Mountain Bridge,near Peekskill, you'd be about 10 minutes away. This could vary w/traffic.....If you're down at say, New Rochelle, NY, you'd be 1 hour away.
Hope this helps,
