My sister Callie was married to Matthew Radmall. They live in Saratoga Springs and have two little boys, Bryson who is 2 and Kace, who is almost 2 months old.
We went on the western carribean cruise where we got to go on a few adventures like cave tubing. It was basically a cave that a river runs through. We were tubing through the cave for about 30 mins. Occasionally when the water got a little shallow our tour guide would turn around to us and yell, "Butts up". 
I am always amazed at the things that David is willing to try. He is afraid of heights, but is such a good sport and always willing to try crazy things like this.
