Damn X, cave diving, you are a brave sob. Sounds thrilling. I enjoy parachuting but I think that is kid stuff compared to cave diving. Haven't been to Cancun but know plenty who have and speak highly of it. I know the resort thing can almost be fake but I think it is a wise decision when in a narco state like Mexico. I'll be curious to hear if you run into a lot of loud fat Americans wearing ugly shirts. I'm an American and as far as I know that is a stereotype but I'm sure they are out their.
