Blue Means Shark!

The National Seashore uses a set of flags to inform (warn?) folks of the condition of the swimming beaches on the Cape. It's a fairly simple set, with the current condition flag posted for all to see on the head lifeguard's chair. The blue flag is for 'Dangerous Marine Life', which includes sharks.

Far, far, more dangerous to swimmers are rip currents. These would be red-flagged. Also, note that there is a beach closed flag, red with a swimmer X'ed out.  We saw this flag last summer after a hurricane missed the Cape, but the waves came on-shore for a few days.
