i got a good sized package in the mail yesterday filled with VT goodies, including the bicycle map.
The bike map looks like it was taken from the same GIS data that you comes from their free VT State roadmap, which means it is mostly highway/county level with a few FRs and smaller roads tossed in. Cerrtainly wont provide you every route. It is marked for paved vrs unpaved and even includes a few marked suitable roads in eastern NY State.
Definitely not as good or detailed as say the old Rubel bike maps were for MA but Rubels weren't free either.
You can definitely map a route to different regions in and around VT and the routes are probably more of a guide than an end-all because I would ride a bunch of the roads that aren't marked as a "safe corridor".
Anyway, its not earth shattering, if you've ridden in VT for a long time or live there, I doubt it would be anything new to you, but for those not from the area, it will provide great information to start planning a VT tour or so.
It also came with the free Road map and also a free camping/lodging guide...
I hope to actually use the bike map in helping with a weekend bike tour...
