The BIG Map of Springfield 
You've seen the Simpsons about a million times. You know all the episodes by heart, but do you know where Three Seasons Motel is in relation to the Little Lisa Recycling Center? Well, thanks to Jerry Lerma and Terry Hogan we have The BIG Map of Springfield. It's a work in progress, but it gives you just about everything you'll need to figure out how far Area 51-A is from Zip Boys. And if maps really aren't your thing, you can check out the List of Springfield. (Thanks Josh)
