It's pretty weird to see facebook-esque pictures of your dad when he was your age, but recently one of his high school friends recently got a facebook and has been scanning in TONS of his photos of my dad and his friends from the 70s. Some of them are really awesome:
Not totally sure how he took this one. 
This is the guy who was taking all these pictures.
My dad's friend as his dad, Halloween 1979
More Halloween, 1979
That's my dad at the tiller.
