On the zoo topic though, here's my experience every time with something like that.
You buy the tickets online. Ow, ouch, F me - kinda pricey. Oh well, it's a special thing, live a little. The kids will love it, right? Fine.
You show up to the zoo (or aquarium or what have you) and are immediately conscious of being surrounded by people that, for all appearances, don't have two nickels to rub together. Seriously, it's like walking into a Council Bluffs Wal-Mart. And how can every woman there between 16 and 50 be pregnant? Or I guess at least give the appearance of being pregnant.
What is the deal with that?
