So, I had about a half an hour before my plane started boarding. I decided to take the Skylink train all the way around DFW airport. I had no idea how long it would take, but I wanted to live dangerously (in a small way, anyhow).
It was a great ride! And totally free. How else would I have gotten such an amazing view of this plane?
Takeaway: how can you add some adventure to your life this week?
