PM a poster named BMIKE.
He can give you a totally Conde Naste'
version of VT. cycling.
I just moved from VT and all I can say is pretty
much anywhere you want to go drivers are very friendly
except for the occasional BMW SUV w/NY tags

and
the scenery is spectacular statewide.
You wont run in to any jampacked roads outside of Burlington
and they're not too bad by almost all other standards.
You will want to err on the side of too many supplies because you
are out in the middle of nowhere in most of the state. If you
break down of run out of water it could turn into a very undesirable situation.
Bring extra clothes too, October at nite can easily be 30 degrees.
Good luck and post a report ?!
