We also bought sunglasses. Because the sun is about to make her brief annual appearance for a month or two and our eyes just aren't accustomed to that much light.
There were so many parent chaperones that I got to drive a car full of adults who couldn't fit (didn't want to fit) on the school buses for the hour's drive to The Oregon Zoo. Which means we got to stop and get a large dose of liquid patience for the day. The large amount of chaperones also meant that I only had to look out for three kiddos, all boys, including my favorite, of course.
It may possibly have been my favorite trip to the zoo ever, wet socks included.
