Many years ago I used to race and build dirt bikes..motocross and enduro..I used to ride along the railroad tracks near my house. It did have a lot of houses backed up to it and by bike had a Bassini pipe (expansion chamber) and was pretty loud. One day this guy was standing on the trail with a shovel cocked backed over his shoulder. I stopped and we had words, did a few wheelies closer. I guess he figured I was ready to run him down,which I was , and lowered the shovel and walked back to his house. I went on my way but figured maybe the noise of my bike was maybe to much for these older folks that lived along these railroad tracks so I found a new place to practice..Now days , I am an old man and more considerate but I do carry a pistol at all times. Any way you look at it , someone coming at you with a shovel is attempted murder , nothing more needs to be said.
