So… it appears that they are going to be hitting up all the tourist traps, even the ones that are ostensibly historical…

And if I wanted to be schooled, I would be focusing on the Sunday installment of Mark Trail, not the dailies…  Yet here we are being instructed on the pre-historic cities, structures and people of Central America…  But with these clues, it looks like they are heading to the Yucatan Peninsula… Cancun?  Cozumel?  Some rustic fishing village where Mark has an old friend that will put them up in hammocks for cheap?
