Zoooooo!

Nathan played hooky from work today (he may have a touch of medical school senioritis, but don't tell him I said so), and we decided to take Tyler & Caroline to the zoo.  A little treat for their almost-6-month-birthday, we said.  To our surprise, it was more fun for us than them (not quite the same effect as the aquarium apparently), and there were actually more "mature" exhibits than we expected.  Either way, they got to see life-sized Sophie Giraffes...  way cool, right?

Whew, tough day... :)
