definately a rider, know who it is.
The first tree i disagree with, the flick through the offset trees at the start of T2 was fun, now it is just faster, this will erode the next corner massively.
The second tree, the 'V' tree, did not flow, was annoying at any time of year, and made people ride around it (another line has appeared). So removing it, improves flow and maintains the original trail line.
At least the person in question is putting some effort into the trails, they don't just maintain themselves, and they don't just come into being by themselves.
I wonder how many people commenting on here have actually performed any trail building/maintenance themselves?
Just get out there and do it, find a puddle that doesn't drain, and drain it, find a blown out corner that people are straightlining, and block the straight route and build the corner right.
