Marciano's a great DM--tons of fun and about as much experience as anyone on AC. He found both turtles and nurse sharks for my kids to see and did a great job with us as a family. And he never uses his fin straps, just rams his ham-sized feet in the pockets and takes off. I think it's suction.

He works, for those of you who don't know him, at Amigos. I already made sure he'd be available for us this year.
He also took a deaf/mute kid named Sherwood (he went by several names it seemed--different ones with different people) out with us several times. He's a local who can't go to school because they've no way to cope with his disabilities--he spends his days hanging around and helping out on the dock at the dive shop. Sherwood's a good diver (I think Marciano taught him) and the folks at Amigos have developed a pseudo-sign language they use to communicate with him. He fell in with my kids and they really got along so Marciano made sure he got on the boats with us. I hope he's there again when we get down in March. We almost wanted to bring him home with us. Man, he'd hate the snow here.
Sorry, pretty unrelated to the thread but just something I wanted to share about the genuinely kind and caring people that make up San Pedro.
