The great white sharks keep coming up the coast to swim off the Jersey Shore.The latest shark to "ping" off the New Jersey coast is Cross, who's just a juvenile male great white shark that weighs around 400 pounds, give or take, and is nearly 10 feet long. Cross's last location was east of Atlantic City, where satellite picked up the signal from the SPOT tag on his dorsal fin Monday evening around sunset. The great whites are on their spring migration from wintering grounds off the southeastern coastal states to the rocky shorelines of New England and Canada where they'll fatten up on seals all summer.
