Man I hate ground level stumps, and I'm surprised how many there are locally. When IMBA visited us in the northeast, they taught us to cut in-trail trees at chest height, and then pole dance with them back and forth until you can loosen up the roots enough to pull/cut them out of the ground. Yeah, you dig a hole, but holes are easy to fill, and I never pedal smack a hole in the ground. And with no rock, we had far deeper roots in the northeast than does CenTX.
