It amazes me when I see this type of post. I think you brought the aggression onto yourself.
This past week, you shared the road with lots of people. At least some of them saw a cyclist giving the double finger to a car full of kids. Nearly all of them saw a fearful grouchy cyclist on the verge of road rage.
How much less aggression would there have been this week if some of those people saw a happy person going about his life? How many people looked at you and said, "wow, he looks like he's enjoying himself. Maybe I'll dig *my* bike out of the garage this weekend!".
How many people saw you share the road with dignity and respect? How many did you inspire to share the road back?
