I have a few questions around the island. It seems every picture you see, no one is swimming. I do not mind sea grass, but have read that bull sharks frequest the area, but I would think that the reef would stop them from coming inland. I am not paraniod, so please do not take it this way, but am curious as to the sightings off shore, if any. Can any verify or dismiss this? As well, what times ar the toll across the bridge to the North open and how much, as we are staying to the north, and would appreciate any info. Thanks.
