Tulum ruins map

Due to a production glitch, the map of the Tulum ruins on p. 144 is slightly wrong. The entrance to the ruins is now on the north side of the walls, and the exit is on the south side. (The general approach is still the same, however.) Unfortunately, this means the text in the book is slightly off-kilter too, as the description starts at the old entrance–but you should be able to get oriented pretty quickly, as the site is quite small.
