What is missing from this picture?

Training wheels!  Yes, the training wheels came off the bike yesterday. 

Bike riding is the favorite activity of our neighborhood right now.  Every day, the kids like to ride bikes up and down our street.

Here is Daddy giving Robert a starting push up the hill....

Robert can usually make it up the hill before stopping.  And when I say stopping, I really mean crashing his bike.

Riding a bike without training wheels requires a lot of concentration (thus, the tongue sticking out of his mouth)

Here is our friend Tess.  She started it all.  When Robert saw her learn to ride without training wheels, he insisted that he learn, too.

I don't think I'm ready for the training wheels to come off.  Now I'm going to worry more about him falling and getting hurt.  It will also be a few weeks until he is good enough to ride a mile or so to the grocery store with me.

While the bike training was going on, Jack and his bff Max were up to no good (climbing on top of cars, etc...).  Here they are saying "no pictures!"
