They do like to ride so who am I to complain. Their mom won't go since we had the baby (who is now 2). She can't stand the thought of not being able to care for him and doesn't like the risk of an accident (She owned her own bike once and rode with me for years before the kid) and I haven't had an accident on the street since 1996!
