Thinking About Moving to Cleveland?

I'm hosting one of the library's new teen librarians this weekend, and I'm putting together a home-spun relocation guide for her. She's young and seems cool, so I'm a little worried that she'll be bored here. But in the interest of helping OCL retain as many of its new hires as possible, I thought that showing her the cool stuff right away would give her a positive first impression and indelibly endear her to the Shore.

So, this project has gotten me started thinking about adding a "relocating to Cleveland?" page to this site, with a list of all the things would-be Cleveland relocators - especially if they're young(ish) and culturally-minded - shouldn't miss.

But it's been slow at the reference desk today and I'm in a terribly sleepy brain fog. So, give me a jump start here. What's your biggest Cleveland must-see?
