I Da Ho Support T-Shirt Photo

"These shirts were made specifically for the Coeur d'Alene Ironman Triathlon in Idaho. The three of us were the Support Hos for our 5 friends who were competing in the Ironman. The back of the shirt says TRI5 2006. We used colors that matched the color scheme of that Ironman and we had FUN! CustomInk made it so easy for us and we were so happy to use the shirts to cheer for our 5 trialthletes!"
