This is "Provide Some Answers," which is a feature where long unresolved plot points are eventually resolved.

Recently, in our reader chat about the Knightfall crossover, we discussed Batman #495, where the Joker and Scarecrow lured the Gotham City Police Department to an abandoned amusement park...

We wondered about why Gotham City had so many abandoned amusement parks.

After all, that's also the set-up for Batman: The Killing Joke.

During No Man's Land, in Batman #569 (by Janet Harvey, Sergio Cariello and Matt Ryan), it is established that there is even a part of Gotham City called "Amusement Mile"...

But WHY is there a whole big area of Gotham City that is just abandoned amusement parks?

Well, reader Tom A., who was in that chat, wrote me with the answer.

In Batman: Streets of Gotham #4 (by Paul Dini, Dustin Nguyen and Derek Fridolfs), we learn that when Gotham City was more of an industrial town, a great war grew up between two businessmen to develop the best amusement park to get all of the spare money from the laborers of Gotham...

When the factories closed, the amusement parks all went out of business and a new villain named the Broker purchased them and began to rent them out to supervillains looking for headquarters...

And there you have it!

Thanks to Tom for the suggestion AND the answer!

If anyone else has a suggestion for a comic book plot that got resolved after a few years (I tend to use two years as the minimum, as otherwise, you're probably just in the middle of the actual initial reveal of the storyline, ya know? But I'll allow exceptions where a new writer takes over a storyline and has to resolve the previous writer's unresolved plots), drop me a line at brianc@cbr.com!
