Birthday Bashing

My 33rd birthday is coming up in just over a month, and I've been wondering how to celebrate it.

30th was a family/friends do in the nature reserve (picnic), 31st was a Chinese braai (stir-fry your own meal over a fire), 32nd was a 5th birthday celebration (3+2=5!) with appropriate kid food, balloons etc. But I'm clueless as to what to do for the double-figures one! This year both my son and I are double figures, he's 11 and I'm 33 - going to be another 11 years until it happens again.

So - I'm throwing this one out into cyberspace. Any suggestions??? Should I just let it slide, or make a big thing of it?
