Sorry no pictures yet from graduation, but I just found another article on David from The Arizona Republic. Sorry that it is so late. I just found it. Here is the link:
If you go to the azcentral northeast section, there is a link to some pictures of the graduations around the valley and David with Mom and Dad is number 10. It is in the middle of the page about half way down under the section called "special." I would post the picture, but there is no link. Sorry!
