Another shot from Pleasantville. Uh, I mean Oak Park. I spotted Dan Bell providing some guidance and a steady hand as his son Jamie, 8, gave it a go without the training wheels on his bicycle yesterday evening. The two raced along Adams St. with young Jamie clearly getting the hang of it as they made their way. Learning to ride a bike is such a defining moment in a young person’s life. It’s one of the first tastes of independence and responsibility.
