Olivia went to a sleepover at a friend's house last weekend and discovered the fun of a Rip Stick. She came home, counted her money and announced that she wanted to go to Target to buy one for herself. It wasn't easy to master, but she stuck with it and can now go all the way down the driveway, turn around and come back. It takes quite a bit of balance.
(And, I KNOW she should be wearing shoes ... believe me! I tried to convince her, but she insists that it will be fine.)
