Library, duh.

Let's set aside the fact that I just finished my M.Ed. in literacy instruction, K?

A library is the bee's knees.

Just walking into a library garners relaxation and excitement all at the same time. (I'm pretty sure the only other place in the world that can do that to a human is Anthropologie.)
I love every section of the library. Turning colorful pages of children's picture books, spinning into a vortex of memories as you pick up books from your own childhood, simply watching young ones giggle with joy over silly stories brings warmth to your chest.
Take a stroll through the numbered non-fiction books and the world of learning is yours! Want to bake the perfect cake? Ask Martha, she'll tell you how to bake the perfectionist's/OCD version. Need to build a deck? Bob Villa at your service!
Then there's the right-brain wing (a.k.a. fiction), the section of the library that takes your from your ho-hum life (apparently we're locked in a library), to every corner of the world, experiencing it through the lens of man, woman, child and beast.
And we haven't even got to the most interesting part of the library...the people. Yes, one could people-watch all day in the library. Children with mothers reading, Dad's working the self-check machine, college students studying, teachers tutoring, teens slumped in beanbag chairs, free-spirited, as well as uptight librarians working, and (if you live in a somewhat metropolis area) a few homeless folks napping behind books, enjoying the air conditioning.

Clearly, the library is the place to be!

Besides, zoos have poop. Like, elephant-size poop.
