We went as a family. It was awesome. Since I work close to there, I could park in our work garage (little one is still too little for bikes), but we were very jealous of the bikes locked up just outside the security checkpoints.
Funny story: I got back to the garage, leaving husband and toddler outside in the cold (they let me bring the newborn in without a security pass), and our car wouldn’t start. Again, wishing we had bike. I tried everything, realized it seemed like a dead battery, and talked to the security people. Luckily they let husband and toddler in without a pass, and they had a kit to jump start cars, which worked, so we were on our way 45 minutes later. But again, we really wished we could have biked.
Oh, and with all of the “trying to get the car to start” I had turned off the normally-automatic headlights. So I ninja’d part of the drive home. When I realized it, I said “Oh, sh*t, I’m a ninja” – husband looked puzzled, realized what I meant, and almost fell out of his seat laughing.
