I wore the Dilly the Dilophosaurus costume in the morning, and Smoky the Bear in the afternoon. (The photo shows someone else in the costume.) The guy who wore Smoky in the morning complained jokingly that I stole all the kids.
The Dilly costume needs at least two people to put it on the wearer. A unique feature of the costume is the metal rack that holds up the head. The head slides over the rack, and a helper needs to feel inside to guide the rack into place.
They fed the volunteers breakfast and lunch, and raffled items from the gift shop, including the book How to Keep Dinosaurs by Robert Mash. I was determined to get that book, so I activated my strange luck. When I was asked to pull a name from the jar, I closed my eyes, stirred the names, and pulled out my own.
Another volunteer was a coworker from my days at the Department of Labor, who I hadn't seen in over eight years.
I didn't wear Smoky for very long in the afternoon because by that time he was very ripe and humid, and my eyes burned from the sweat. As soon as I got home, I took a shower, and my apartment still smells of funky dinosaur and bear.
I heard that the turnout for the event by afternoon was about 1500 people.
