What do you do when you're a super famous A-list celebrity and you can pretty much do whatever you want?
You hang out with other super famous A-listers as well! Duh!

Damon was also seen riding a horse drawn cart. Such a cool job he has, getting to play make believe with a real live horse.
That is one cute horsie!
Lookin' good you too! Keep up the film making!
