I invited family and friends from around the world to send me a rock so that I could build a cairn on my 60th birthday, April 24, 2003. As a hiker, I rely on cairns on the trail to point the way. But this cairn also signified a way point in my life. I received more than a hundred rocks.

Cairn 2003

Ten years later I invited new family and friends to send me a rock to add to the  
Cairn on my 70th birthday.
