K was gracious enough to go into the Texas Sized Human Maze (as seen on Amazing Race 5). It took us 30 minutes, but only because we had a task to complete. We found the exit several times, but finding the "Z" to get our little card punched was what killed our time. The other letters were fairly easy to find.
Along the way, we encountered signs of "You've been here before", "Short Cut", and "Are you lost?". Amusing, but none were terribly helpful. :)
