I like it.
I rode the new Greenbush single track this last weekend, I think it's very promising and a huge improvement over the old biking/ski trails that I would normally ride their. I rode my new SS bike, Man was that a blast! I can't wait to ride it again, the bike is northing fancy but just pure fun, I had absolutely no problems on the climbs it sometimes felt like I was actually climbing faster who knows though I could of just been having a good day.
Being a resident of Oshkosh I am pumped about the new Single track, Greenbush is the closest trail to my house.
