Old Man Travis is turning 30 in about a month and I need to throw a party for him. Any suggestions on what to do for a 30th bday party?

The first thing that came to mind was an 80's themed party because he was born in 1981, but that just seems too easy. I could still go with that, but was wondering if people had better ideas. There's always the black/over-the-hill theme, too, but I feel like that's better suited for a 40th bday.

I'm thinking a keg and beerpong are needed, too.
