Portions of this trail had a machine of one type or another, portions didn't. I'd point it out which, but that would take away some of the fun. Much of this topo was too steep or rocky for a machine. They used a machine where it was possible.
Below, I'll call mine. It's not blessed with rocks like Massanutten but it's machine built/hand finished. Pretty fast/flowing, intended as beginner/intermediate trail.
Most of the trail in this video where built with a 5ft mini-excavator (Deere 27D) with hand finish, some with a 4ft mini-X (Deere 17D) with some help from a Ditch Witch SK650. The oldest trail in this video is 3 years old. Vegetation grow fast around here.
I grew up in Vt at lake Champlain & Quebec boarder. I head back every fall for deer hunting just N of Island Pond on the Vt/NH boarder. Was just there in the summer for a reunion and road some of the trails in the area. Missed it. Heading back 11/7 for the month. Where are you out of?
I'm in Granby, just next to Bromont, QC. We build mostly all over QC, but work across Canada.
Depending when you're around, give me a shout. We're expecting twins baby girls sometime in November so I might not be available. At the very least, you can come over for a beer or I can find you a guide to show you our trails
