scooting around the park

This afternoon the kids and I met up with a friend at a Farmer's Market for lunch/snacks and play. We all had a great time, but Meredith was disappointed she couldn't ride her scooter (the playground didn't have any hard surfaces). Afterwards, on our way to the grocery store, we stopped at a park so they could ride around. Both kids are getting really good, often going much faster than I feel comfortable seeing. Today I told Meredith to slow it down when she seemed to be losing control. Her response? "But I like to go fast!!" She's always trying to keep up with her big brother.
