How many generations does it take to build a shed?

On a cold February day, my Dad came over to help Danny build his shed. Two little helpers were totally undeterred by the cold and were determined to make themselves useful.

I need to dig through my Mom's photos, because somewhere we have snap shots from 20 years ago of my little brother helping my Dad and my Grandfather build a fence in the backyard.  

There's something special about three generations working together.
