The good news is, I wasn't pregnant this year when we went. The bad news is, I still (foolishly) didn't take another grown-up with me for back-up. I figured it would be a breeze having Noah on the outside this time. It wasn't!
It was still a fun and very educational day, and we actually watched part of the air show this year after we finished in the kid area. Unfortunately I forgot to charge my camera battery the night before and it died before I could take any pictures of the planes flying. I laughed when the camera said "battery exhausted" because that is exactly how i felt!
