I may have mentioned this but:
Heading under the Long Island Bridge Eastbound towards 19 Mile coming from Trexlers after you go under the bridge to your right about 100 yards North/Northeast there is a rock that I feel should be marked.

Cuz I hit it a few years ago.
However, as I was checking my prop a Marine Patrol Boat hit it too!
I was busy checking my outdrive for damage when I looked up just in time to see and hear a carunch! I motored over to him as he was checking his prop and asked him if he thought there oughtta be a marker there? He mumbled something and shrugged. I think he was embarassed. I felt better about my mishap after that.

I did feel bad for him but not so much as it wasn't his personal boat.
