A bit obscure maybe?
I'd be truly astounded if anyone ever gets 10 on this one. It is easy to write impossibly difficult walls. The goal is to write ones where the response, after seeing the answers, is to say, "I should have seen that!".

The Poughkeepsie line is probably too obscure; it's there just for the bit of fun in seeing if anyone was familiar with the link. I wouldn't call the rest obscure; an immensely popular novella, major cities, and some of the biggest names in a sport don't seem ridiculously elusive.
