Went for a ride on the beautiful fall morning and crossed a relatively narrow, pedestrian bridge from PA into NJ. There were large, clear signs for riders to walk their bikes across the bridge. I was walking with a few folks: a young couple with a small child and a few guys from a car club, when a rider approached from the opposite direction. After he passed several of the folks made comments and some asked me about the rider. Obviously, I didn't have any answers why he decided to ignore the signs. For some dumb reason, I felt a little guilty because of this.
It only took a minute or two to walk across the bridge. This really wasn't dangerous, just inconsiderate in my opinion. I also had a distaste for someone I would be lumped in with, giving a figurative black eye to a group.
I was better a few miles later, just wished he took the time.
