Another birthday gift from Grandma and Grandpa to the kids was a trip to Austin Bouldering Project, a rock climbing gym. The kids often try the rock climbing wall when we are at events and it's free, and last month after doing it at the baseball event, they all were very enthusiastic about trying it at a rock climbing gym. In fact, they could hardly wait to try, so we went today. Johan got an early gift from Grandma and Grandpa, so it worked out well.
They LOVED it! Technically, this was a bouldering gym where all of the walls are relatively low to the ground with a thick pad, and no harness is necessary. I think that made it all the more fun and less scary. They started on the kiddie wall, but quickly got bored with that and begged us to take them to the adult section. I suppose because they have so little weight to pull around, they just scrambled up some of those walls.
