The Cabot Trail is great, but it only takes a couple of (leisurely) days to ride it.
This is why I'm thinking of trailering out to the NB area and just doing the coastal stuff in 3-4 days, and then trailering home. I'm in the process of starting a custom trailer now, frame is in the driveway.
The biggest issue we had was the weather. We went in late June, and it was COLD and rainy much of the time. I'm talking six or seven degrees on the Cabot Trail.
This was something a fellow rider mentioned to me last night while out for coffee. Not something I expected. I've been to the coast lots of time all through ME and Fundy as you did, but not right to the far northeastern edge of it...guess the weather is different out there. Was kind thinking we'd be looking at sometime in August honestly, are things downhill after June however?
