Robert, Steve, Larry
My dad and his brothers. I'm not too sure who's in the middle - possibly a cousin?
My dad, Robert, is on the right. My uncle Steve is on the left. And my uncle Larry is having his face covered by the unknown guy in the middle. The hazards of being the much-younger brother!
It looks like it was taken the same day as this photo: www.flickr.com/photos/ursa_major/3801525319/
In that one, you can see that the Volkswagen behind them is from Kansas, so perhaps the person in the middle is a visiting cousin.
