The kids and I love collecting waves. The idea is simple: try to get other people to wave to you. Each wave counts as a point. Here’s the article in the Chronicle about it. It’s not so much a competitive sport as it is a challenge to see how many we can get as a group.

A few weekends back, we camped at the Disney campground with my nine-year-old’s cub scout troop. On Saturday, his little brother and I took the boat to the Magic Kingdom while he and his mom did the scouting thing.

The day was beautiful, so  we sat on the back deck instead of staying inside. As we rode to the park, I decided to issue a challenge. “How many waves you think we’ll get?” I asked. “I’m gonna say fifty.”

“Hmm.” He looked around, then rubbed his chin as if he were thinking hard. “I’m gonna say two thousand.”

“Two thousand?” I laughed. “There’s no way! Once we get to a hundred, we’re going to be too tired counting to keep going.”

He smiled at me, his eyes twinkling, and gestured off the side of the boat. “Lot of waves out there.”

Our eyes met, and he burst out laughing.

“Okay,” I said. “You win. Two thousand, it is.”
