The trail in a local wooded area got messed up by some bicyclists who built little jumps in it, using dirt and pieces of logs. It was an annoyance to walk around the jumps. The solution was to destroy them, returning the trail to its original condition. Here I am about to begin working on the first of three such abominations. In about 90 minutes the work was complete.

My assistant, Joe Tripod, doesn't work with shovels, but he digs this type of assignment.
