No More Training Wheels!

It's as if Zach has been riding his bike without training wheels for years. Off and on over the past couple of months, we have been taking Zach out to our backyard on the grass, trying to teach him how to ride his bike (without the training wheels). We weren't making much progress. This past Sunday, Zach asked if he could try riding his bike in the cul-de-sac. Of course, we were hesitant because we would be dealing with concrete and we had not done this before. Well, after holding/guiding him around the cul-de-sac two times, Zach started riding by himself! Seriousy, he does not need any help. Now, the only downside is that all Zach wants to do is ride his bike (ALL THE TIME).
