Augusta to Bar Harbor, Maine. used "Bluenose" ferry to Yarmouth, Nova Scotia, Canada (NSCA). i went to Halifax, headed west to Turo, then through Cabot Trail, , but wiped out at Breton Cove. people at camp took me to Sydney so i could rebuild rear destroyed wheel at LBS. picked tour back up, , went back through Troy but inland this time, saw Bay of Fundy, Bridgetown, back to Yarmouth. after ferry back to USA, i met some kids at Cadilac Mountain, Maine. they gave me a ride to Augusta!
i did this tour solo after x-USA (Bikecentenial, e-w, 1982). our tour leader stated that: "if you ever tour again, tour NSCA!" i took him up on that, will never regret the choice!
if you want further info, let me know. i am aware that my data is dated, but am enthusiastic about your venture!
