Back from an overnight

We rode a bus to Chicago overnight with UWSP's Adventure Tours.  We saw "The Outsiders" and toured the extensive underground system of walkways that people can use to get to major stores and offices without being in winter weather.  Lynn predicted it might be more walking than we could manage.  What?  Pooh!  

She was quite right, as usual.  Guess which one of us got exhausted to the point of staggering?  She wants me to include the tour of the Museum of Science and Industry so I am.  I ended up staggering along, looking evidently as though I might die.  I haven't.  We are both slowly recovering, even more fully grasping that we are genuinely elderly.
