Mexico, Yucatan, Playa del Carmen, Snorkling.
Even though it was really way too windy (which makes the best spots unavailable, and the sand degrades the clearity of the water), we went snorkling our first day. At least we got one of the mandatory things-to-do out of the way :-) This would probably be a spectacular view under better conditions..
This also served as a reminder of just how much consumer-grade 400asa print film suck..
