This is a different kind of map than most here would probably expect to see here. It's a map of a baseball field, for use in my D20 conversion of the game of baseball. It's very similar to the dimensions of a regulation baseball diamond, differing at most by only 6".
This image was made largely in Illustrator CS3, with a rasterization in Photoshop CS3.
