Heading East from Montreal

Highway 20 is BORING. Take the smaller highways south if you have time. I took the 165-112-216 combination. Speed limit is 90 km/h, but you'll be passed if you aren't going at least 110 km/h. Highway 165 south is amazing. Hills, valleys and twisties. You'll be hard pressed to find a straightaway. Highway 216 was a bit bumpy in patches - you might actually get closer to 90 km/h there. But still hands down a better alternative than highway 20.
