Every now and then we would look up and see sky through the cave ceiling. Light poured down in a cloudy beam- illuminating the rocks at the bottom of the pool like a mini-spotlight. Beautiful. A few bats clung to the top of the cave, and small fish swam about our legs. We took a few pictures, but of course the underwater photos did absolutely no justice to the beauty we saw- a few panoramic shots will give you an idea of what I'm talking about though.
PS- I forgot to mention that we met some girls from the US while we were visiting the cenotes. One girl was actually from Houston and went to Booker T., but they all met while going to school at Morris Brown College in Atlanta, GA; they were celebrating a 30th birthday- man, what a way to celebrate! Heh... funny how it's always nice to talk with someone from home.
