When I turned 10, it was just a normal kid's birthday, and I went to see Honey, I Shrunk the Kids on top of it. When I turned 20, not much. My father was visiting Iran overseas, while I was at home. It was pretty much just another day. Not that turning 20 was a Huge Deal to begin with. It was sandwiched between 18 -- when I went hiking in New Hampshire -- and 21, where the first thing I did when I woke up was buy a beer for the sole reason of because I could, and then went to the bar at night. So 30 was the first birthday where having a Zero at the end had any significance. I went to Top of the Hub in Boston. A rotating restaurant on the 52nd floor of a skyscraper. I wanted to do Something Big for 40 too. I hit the big Four-Oh in a month-and-a-half. I wanted to go to Hawaii. Then I scaled that down to wanting to see the Enterprise exhibit in New York. But now my money situation kind of sucks. Actually, not "kind of". It's pretty bad. But I only hit a decade-milestone once every 10 years, so I should do something even if the snapshot turning 40 caught me at isn't so great. So what do you do for these types of birthdays or what do you recommend? Don't say "treat it like just another day" because that's not what I'm going to do. And what have you done on your zero-ending birthdays?
