It's been a great weekend.  My son has learned to ride his bicycle without using training wheels!  Riding a bicycle is one of those childhood milestones that is met with such anticipation (like a baby learning how to crawl, then walk, riding a bicycle is a symbol of further independence).  I personally didn't learn how to ride a bike until my adulthood (growing up in New York City, it seemed like everyone just walked everywhere).  Now my daugther is itching to ditch her tricycle but she can hardly reach the pedals of the smallest bike.
