Hi Jorge,
Just cruising and notice you and I both live in Portland. I got a KH29 in December. I am into it pretty good at this point. I discovered a trail up in Boring at the end of the Springwater bike trail. The last 2.4 miles of are unpaved which I prefer. Then there is a 3 mile gravel trail called Cazadero trail right there too. Yesterday I did both loops back to back for a total of 11 miles. Have yet to meet anyone to uni with. Probably not looking in the right places.
