Why is this becoming a road biking loop 😡 it's unfortunate to see everything becoming wide boring gree flow trails - might as well pave this while you're at it

Trees all cleared out. Fun old school ride.

Agree with the previous comment. Also quite a bit of knock downed trees and low hanging branches.
We hope you've been enjoying Trailforks!
