I arrived in Palenque without a plan, only to learn that my choices to get out of town were either the night bus to Chetumal, on the border of Mexico and Belize, from where I could travel south through Belize and back to Honduras; or, I could travel south toward San Cristóbal de las Casas, and make my way back to Honduras via Guatemala.
Traveling to Chetmual meant route 186 in Tabasco, which at night is known for its thieves and highway robbers. Traveling to San Cristóbal meant roadblocks. Why exactly, I never quite figured out. Probably something to do with narco-politics. I chose the roadblocks, mostly because I preferred Xela and Guatemala City more than backtracking through Belize.
