If there's one thing I know for sure, it's that children can both lead the way and changethe future. It is my pleasureto know this hero, my cancer survivor friend: Harrison Strickler. To say that he is well on his way to changing the world...on his bike... with his yellow jersey ...I might not be capturing the real essence of this great kid.

My family and Harrison's have grown up along side one another, and I have always known that this little boy was someone special. His amazing determination was there long before the cancer cells. During the early days of his battle with leukemia, many a dinner conversation at our house unfolded as we all learned about living with courage and purpose.

The "why's" and "how's" of cancer are tough questions to ask and to answer, but to see my own children grasp the magnitude of it all...I have a lot of gratitude for what Harrison is teaching us with his life.

To that end, as a family we now spend Father's Day every year raising money with Harrison and the Rally Foundation for childhood cancer research. Next year, I hope you'll pull out your bike and ride with us. There is nothing finer than seeing children who selflessly get it: "I have only one ride through this world, and I'm going to make sure it's the best ride of my life!"

We change the world by what we teach our children. Thanks, Harrison, for lessons I couldn't come close to teaching as well as you. Ride on!
