Yesterday, a busy Sunday, I was riding on a trail around one of the beautiful Minnesota lakes. When I came to the beach area, I had to stop and walk my bike around an elderly lady whose dog was on a very long leash. The leash went entirely across the trail. The dog was very large. When I stopped and walked around I politely suggested she may want to pull her dog to her side for safety when she sees roller skaters or bicycles coming toward her. I won't bother to tell you her reply.
