Frightening in the sense that I gave squinty-eyed stares to every passing car, and said "Listen. I have even less control over myself, so if you pull out in front of me there is a good chance that we will collide, and I very seriously doubt that you will get the image of me splattered on the road out of your head any time soon, so just slow on down there buddy". Exhilarating in the sense of "Yes. I am a badass."
I also wore a skirt that was short enough so that, when I dismounted, I flashed a few passerbys. That was also a little exhilarating. For posterity's sake, I will also note that I wore a coat, hat, gloves, and leg warmers. It was chilly folks!
