We have gone three times in the past three weeks, and we are in love:
And yes, I get to climb, too! Although on the field trip with our homeschool group I stuck to belaying all the children, on the field trip with my Girl Scout troop Matt was able to come, as well, so he and I could take turns belaying each other:
I HIGHLY recommend rock climbing. In fact, I can't believe that we haven't gone before this! It's great exercise, in that it's both accessible (no matter how out of shape you are, you can get at least a little way up the wall) and super-challenging, it's an excellent family bonding activity, it wears the kids out so that they sleep really well that night...
...and it's fun!
