Reesha, I totally empathize with you. I don't like steep downhills, either. I had to ride down one really steep one on our tour last summer, which ended in downtown Ithaca, NY. I was frozen at the top, with DH yelling at me to just get on with it! Yeah, and the hill ended at a stoplight in rush hour traffic. I did it, but I would have preferred walking. Oh, and it was partial cobblestones. Then there was the downhill I did walk in western MA. It was a rutted, rocky dirt road and I was on my road bike. I would have been scared on a mountain bike!
