That Halterman dad has some SRONG genes! I've seen a pic of the mom, Barb, and it doesn't look like the kids get it from her side.
Guy next to Michael is Jason, who was married to Amanda and is the father of their 4 boys.
Guy in the water is Braxton, Amanda's oldest son.
I caught a glimpse of one of Amy's sons and he looks like he has those Halterman genes, as well.
You could see from space that Angela and Michael are siblings!
