Not saying there's anything wrong with having a map. I'm the sort of cartographic nerd who thinks there's no such thing as too many maps.
What on earth are you going to do with a map of Cozumel dive sites, though?
Ah, our dive operator lets us pick the sites we dive. I like to lobby my group the night before.

Waterproof? As we all know the term lobbying was coined for the practice of hanging out in the lobby of a hotel where the bar was. I've searched, but have not found a map that boasted it was beer proof.
