Last summer, my son turned thirteen.  We decided to try something new for his birthday party.  I have a friend who owns a rock wall climbing business.  So, we booked the party through him and it was great.  The kids all had to have signed waivers before they could climb the rock wall, but they loved it.  It was a great experience for all the boys and it really gave them confidence since they tackled something new.  Some of them even learned how to be the anchor and help they friends climb.  I know this is something we will be doing again!
