Miles2go,
The wife and I just did the Green Mountain Loop (or most of it) We took a few detours to follow the railways and abandoned rail beds. As we are both also train geeks as well. If you get a chance ride the rail bed from ST. Albans to Richford VT. 26 miles of farms, wildflowers and songbirds. It can be ridden with any type of bike as the surface is a fine crushed limestone, we rode our fully loaded LWB recumbent tandem on it with out any problems.
