Absolutely no rush on this, as this ride probably won't take place until the spring of 2012...

Anyway, I'd like my wife to see the northern section of the Westchester County Trailway one of these days. She's not much of a rider, but she enjoys getting out on a bike, especially when I find her a good downhill/one way path somewhere.

I haven't done the North County Trailway in a few years, so I don't remember exactly how hilly it was. I rode it from south to north, as far as Baldwin Place, which was pretty much the end of the trailway back then. But I do remember some good scenery and some cool little towns like Yorktown Heights, etc.

I'm thinking I'd like to find a 10-15 mile section toward the northern end that is:

A. mostly downhill or flat going either north or south
B. accessible to train stations at both ends

Can anybody make a suggestion?
