This past fall (2009) I was back in the for a weekend and had called David to see if he wanted to go for a bike ride one of the days. Schedules worked, Misha joined as well, and the three of us climbed up to Skyline and back on a Sunday early afternoon. When we returned, Misha had to head back north to the City, but I had a couple more hours so stayed and hung out with David and the girls in the backyard while Melissa went to run some errands. The girls had all kinds of entertainment out back. The swing set, climbing structures, tents set up, etc. David and I watched Annika on the grass, trying at times to have an adult (likely a work) conversation while Caroline continuously called to show him how high she was swinging. Meanwhile, Sierra had her bike out. Despite being younger (or perhaps because of it!) than Katrina and Caroline, Sierra always seemed to be the dare-devil. She already knew how to ride her bike without training wheels and had no fear. She would circle the pool until reaching the step up, get off, pull the bike up, cycle half-way around to the step down, get off, repeat. As David watched her, you could see them both beginning to think how much easier it would be if she didn't have to get off the bike on the downstep. I don't remember if he suggested it, or if she asked - but before long, I was left on the grass with Annika while David spotted Sierra in her first "jump" off the step. He coached her to peddle steadily and not slow down and encouraged her as she hesitated that first time. She landed the very first one with his hands barely on her, wobbled a bit but stayed up right and rode on around the pool. Over and over she would reposition herself and start cycling straight at the step! Pretty soon, David didn't even have to stand and spot. Needless to say, he knew full well what Melissa would say about this new activity when she found out! But you could see his own excitement and spirit of adventure in his enjoyment of his dare-devil daughter exploring her own boundries. It was a great afternoon.
