Thanks for the info fellas. I'm thinking since I'm only going to have about 1 day to really fish the flats hard, my money is probably better spent on a guide who can put me on fish rather than spending the time just trying to find them. Although I do love DIY and have done so successfully on a number of islands including Aruba, Bonaire, Little Cayman and others, I don't get to fish nearly as much as I used to (family) so need to make the best of it.
When I was in the BVIs about 10 years ago, I did catch a bone on St. John near the Anaberg? ruins. Also caught a 50lb tarpon on fly from our boat moored in Cane Garden bay.
