I know what your talking about. Last year Dani (AKA "BlueEyedMergerer") snitched our favorite diver spot...the legendary "diver grounds" Since everyone else knows where it is, I figured I'd share it with you good folks (Im assuming your duckboat goes about 20mph and burns about two gallons of fuel per hour--six gallon tank):
Head east-Northeast from the St. Augustine, Florida inlet (Matanzas for all of you Huguenot-hating Spaniardphiles). Travel for three hours. When the water turns purple, your there. For some strange reason, theres a geological anomaly which fries electronics, so leave the radio at home...
email me if you want the coordinates. Oh, and it only goes off when a Northeaster or, better yet, freak late season hurricane is heading up from the balmy carribbean -- but keep that little tidbit a secret, eh?
You are welcome, in advance.
