Z - It's a Zoo Out There!

Our last letter, Z.  It's a Zoo Out There was bought at Goodwill for $2.69.  How could I resist!  There must be a story behind this trio of Washington D.C. powerhouses!  The title is one I picked for the Challenge, I usually call it Animals in D.C. 

A Z poem is here. 

This is the end of another April A to Z Blogging Challenge.  It's always fun to participate, and read so many other A to Z posts.  Come back soon, I post multiple times a week beyond April!
