I remember the 2001 maps looking a bit differently (sorta like the older 2000 maps). I'm pretty sure the park used those for a short period of time before converting to the maps found in the brochure *shudders* those were awful.
On another note, I snagged a few map shots. If they need to be resized, (they are fairly large) just tell me. And for a little extra, I've got a shot of the map from the week Mach Tower opened.
