Good map of a high school

[Creature Feature]

What kind of school are you thinking off? Mutants and Masterminds 2nd Edition had a few splats about their version of Xavier's that was made to train young superheroes. No doubt those will have a floor plan that's usable for your cause if you're looking for an institution with built-in danger room.

Otherwise, Google's Image Search gives a few example floor plans as the first few results.

I can't find anything "Map Tools ready", I'm afraid!
