Took the Klein out on a couple of roads I haven't done - one for several years and the other was the first time on it (other than walking). Both were quite rough and the legs and arms got a pretty good workout on the downhill. The heart got a real good work out on the first half as it was all climbing.
Already climbing on rocks for 3/4 mile or so
Onto the power line road
You go up quickly on this road:

Note to self - lower the psi for this road next time:
