The Summer of Shark Attacks: Watch out, South Beach, Miami or all Florida! The sharks are coming. Please be careful when enjoying the beach and the waters. Two attacks so far! One is fatal and the other one is serious. Please swim where a lifeguard is on post. Watch your surroundings. If you see lots of feeding activities around you, don't wait. Get out. If you are between sandbars, then just know there could be some sharks lurking around. Sandbars are their feeding grounds.
