DriveThruRPG (rpg.drivethrustuff.com) is having a "DM's Day" sale this weekend. Was looking through the sale stuff and came across Heroic Maps, a collection of a PDF maps that, according to the site, were originally designed for HeroQuest. Since the packs are less than $3 each, I will be picking up a few to check out. They look pretty cool - they have a bunch of outdoors/wilderness settings, and their underground maps have some cool layouts.
They definitely look like they will work well with HeroQuest!
