But I want a skycab!

I like the way that sounds.

For McDonald's, I don't know about MDW, but at our airport, there's a sign that says something like "please be aware that we offer a limited menu before 5:00am" or maybe it's 5:30. I don't know what that means, and I'm not sure if that's because I've never ordered early enough to be in the limited menu period, or if I've just never ordered something that wasn't available at any time.
In any case, have a good flight, whenever it is!
