Birthday decor

My dad's 60th birthday is coming up, and our family is renting a house in the Poconos where we can come together to celebrate. I can't wait. I've been brainstorming decor ideas and love this photo from Martha Stewart Living.

What did you do for your parents' sixtieth birthdays (if they've had them yet)? It's a big one!

P.S. Birthday cheese, and a birthday installation.
