The route chosen is up to you! Most,, not all,,, Head to Buffalo first. (I did ),, then across the Pease Bridge, etc, etc, etc... One thing to keep in mind,,, at the Detroit end, you CAN NOT take a motorcycle thru the tunnels !!!! You must cross over into the USA by the Ambassador Bridge.. I had no problem getting fuel, (except for cost). It's a very enjoyable challenge !
