Folks, be warned. I tried to download the cruising guide below, my anti-virus just about had kittens, one of those "call us to get your PC back" sites.
I'm going to contact Rick the original poster, he may not be aware.
There's a free soft guide (pdf file) called "A Cruising Guide to Puerto Rico," Ed. 1.3, by, Frank Virgintino.
It's good.
It's 205 pages and 34MB in size. I downloaded it a couple of years ago. If anybody wants it, drop me a PM with your email address and I can send it to you.
