YOSEMITE, Calif. (BP)--Wow! Wow! Wow! That's all I can say about July 15. I can't believe that I went rock climbing in Yosemite -- especially since I can't stand heights. When the TruthQuest team rappelled off a 30-foot high rock, it took me forever to get down. After I finally returned to the ground, I thought our adventure was over. However, North American Mission Board missionary Steve Hughes told us that we should conquer a bigger rock to have a better feeling.
