This is the judge's diagram of the track on which Chelsea earned her TDX. It's not really a very revealing diagram. The area was hilly and the track went in and out of treed areas (including poison oak) and meadow areas. For the story of this track , click on Chelsea's TDX Victory, which has her victory photo, our victory song, and the story of the track. Chelsea was an old dog at this time , with a lot of arthritis in her hips. She still loved to track, but could no longer pull hard. She should have earned her TDX at several earlier occasions, where she tracked beautifully but I screwed up badly as handler.
