I was riding about 25 miles per hour on the morning commute, going through a park. Out of the corner of my eye, I saw a dog darting towards me. Helpless, I knew that I couldn’t stop in time and, sure enough……..CRASH!! My front bike wheel rammed right into the dog and I fell onto the ground. Its a good thing I had a helmet on because my head slammed hard into the ground. But, fortunately, the helmet absorbed everything. I scolded the owner, who apologized to me, for not keeping the dog on a leash. No major injuries though. Without a helmet, I might be brain dead right now.
