If I dig deep enough, do you think there's a cenote there?

What do you think it would cost me to build one of these in my backyard?

Cenotes are limestone sinkholes with underground rivers running through them found throughout the Yucatan Peninsula.  These cenotes were sacred places for the Maya and were believed to be the entrance to the underworld.  Filled with crystal clear fresh water, they are absolutely on our favorite places to go.  Some are completely underground like the one we visited in Chocholá, where you could barely even stand, and others are open like the one near Chichén-Itzá (see pics above).  Regardless, the most impressive are the cenotes we visit in Cuzamá.  Get prepared to be jealous!
Pictures and videos to come.
