Trip was great! The 100 or so Km stretch of road from Baie-Comeau, Quebec, was probably the best road on the entire trip. Labrador was one rainy mess - but we got through itl. Some big pot holes on the dirt roads, especially between Port-Hope-Simpson and Red Bay. Overall, everything was enjoyable, except maybe Maine between New Brunswick and New Hampshire was lame.
I'd say good choice of bikes (F700GS and F800GS), and good thing we put on knobby tires (slightly deflated) over the dirty bits, as none of us had any punctures - but we talked to many other bikers and drivers who did. My tire had a big gash at one point, but I guess it didn't puncture the tube on the inside, so we were able to keep going.
Had a great time in general, no incidents, aside from my reserve fuel canister falling off my bike - which could have turned into a much worse situation than it had. The F700GS had some minor electrical issues, but we rode about 3 days of heavy rain, so I guess it took a toll on the thing. Too many great memories to recall them all here though.
