If you are watching this season of The Amazing Race, you'll know that one of the competitors has Asperger's Syndrome, which is a form of autism.
One of the road blocks on the first episode involved herding ducks. I was thinking that I bet the man with Asperger's would do a great job if he is anything like my Caleb.
A couple of the other competitors called him the duck whisperer.
Caleb sure loves the ducks and geese at Grandma and Grandpa Greer's house. They love to follow him around and he'd just march around with them all day.
