A Little Bit of Austin

Tomorrow is an extra early flight to Cancun, so today is a day to prepare.  We have had a little time to explore Austin, so I checked out the Lyndon B Johnson Library and Museum.  I like history, but I was a little disappointed to learn that I couldn't actually look at any books.  I've enjoyed Austin, and I'm looking forward to beginning our time in Mexico tomorrow.

What did I observe?
