Misty and I are about to head for the zocalo in San Cristobal de las Casas in Chiapas, where we are doing the colonial city leg of our month-long road trip driving from Texas, clockwise around the Yucatan, then down to Chiapas and back north. Tonight is "cook your traditional dinner for Christmas" at the hostel, but I am balking about attending, all curmudgeonliness aside: the Europeans would never believe that in Texas, we eat tamales for Christmas.
