Liam has discovered that he can actually ride a bike, he provides the pedal-power and I steer. Camper is kind of like our horn; he's yelling most of the time.
Seriously, when Liam starts pedaling, it really pushes me along. We'll be coming up to an intersection and I'll yell, "green light! Pedal, pedal, pedal!" and I can feel the bike accelerate as he really starts pushing.
On the flats, I stop pedaling completely and let him provide the power. He loves it. He'll yell, "check it out Daddy, I can push you and pull Camper at the same time!
We were driving around east Portland yesterday. I can't wait for us to move into PDX and have access to the Springwater Corridor and Eastbank Esplanade.
