I was trucking through a city that gets a bad rap among people in my line of work when I came up with the idea to "modify" my gearshift while stuck in a traffic jam. Imagine a hostile party jumping onto the side of my cab demanding money only to be greeted by the ultimate surprise.
(Nothing actually happened. The city turned out not to be so tough that day. I really just wanted to see if I could mount my favorite blade in a location that was easy to each from my driver's seat).
