This is truly sad -- there's something about smaller kids on bikes that scares me; not just because I have two of my own.
I was driving Moraga Way through Orinda the other day and saw a young girl can't have been more than 9 or 10 riding a MTB solo down the narrow shoulder. Anyone who lives in the area can probably relate - I don't enjoy the road as an adult, but that kind of thing just sends shivers down my spine.
