Dear Mr. Rossage,
I believe that "Ding Dong" is an Orange County Trail that Mr. Mike is referencing. The "Ding Dong" in Lebec YOU are referring to is a completly "different" matter...
DD is the singletrack that peels right off Bell Ridge (Santa Anas), dropping into the Trabuco drainage near the RC airport.
The trail name is ridiculous compared to the riding on it. It's loaded with just-right difficulty steep turns and tricky passages – which are a little more challenging once you get to them after Bell Ridge. It's a little worked with ruts and a few blown out areas, so it's nice to see the trail getting some love. Thanks, whomever...
