Where's Diego?????

While looking at the following pictures your main question might (and probably should) be "Why are those grown men denying that toddler the chance to ride the rocking horse?" or "Who knew Trent and Brad were so into pastel rocking horses?", but you would be wrong, the real question is, as always "Where in the world is Diego Herrera?"

These are the guys in Jay's residency class. Trent, Graham, and Brad (minus Dave and Diego). Diego seems to always miss the group shots, so it is a running joke - Where's Diego?
