It's a cool, calm, breezy evening in the Caribbean. It's 12:17 a.m. and it's been a long day, but I'm not quite ready to sleep yet.
We're anchored off the island of Canouan, in St. Vincent and the Grenadines, and day 12 of our three-week trip has come to an end. Already we've done 26 dives and completed Advanced Open Water and three specialty diver courses, as well as Emergency First Response. Tomorrow we begin rescue skills practice, and at the end of the trip we'll have a week to devote to fun diving and specialties,
