Some kids at the school I work at started calling out at my bike when I was leaving. First call,--laughter--and then, "That is a weird bike." Next kid yelled, "Hey, cool ride." Next one hollered, "When do I get a test ride?"
Then, on the way home today, 2 groups of kids called out. First group was incomprehensible (I was going too fast), but they were all smiling and waving. Second group called out, "Cool bike!"
...Kids know a good bike better than anyone else does.
