One fall weekend, my wife and I were driving north on Interstate 270, going from Urbana to Frederick, Maryland, when we spotted a sign saying "Scenic Overlook." We had some time to kill so we took the exit. It was a nice place to stop because there's a great view of the city of Frederick, tucked into this valley that's bordered by the Catoctin Mountain, the eastern most ridge of the Blue Ridge Mountains.
As we were walking back to the parking lot, I noticed a group of people gathered around a small truck. My curiosity got the best of me, and I wandered over and found an elderly couple explaining a problem they were having with their vehicle. They had pulled off of the road, not for the view, but because the left front brake was staying on all the time making the wheel very hot (and very dangerous to touch). They clearly had honed in on the problem because each time the wind shifted and blew in our direction, the distinct smell of burning brake pads flooded our nostrils.
