If you go to tmca.nu there is a destination wiki site on the top left that I created using all the best information out there and my own personal data. Use that as an additional guide. Buffy and Jay book is great and we used it sailing to Army Hole on Matagorda Island where we meet them when he was writing his next edition.
I created a booklet of Cruising Destinations on the Gulf Coast called a Quickie as a pdf for your digital tablets and soon a waterproof booklet. I was so frustrated with the big textbooks of cruising info. So I created a quick reference guide for uptodate anchorages, restaurants, marina, weather, and cruising aids for each Gulf Coast state.
