National Treasures' Moonlight walk to Fort Charlotte will take place on Saturday, 31st March starting at 7.00 p.m. The walk is possible due to the assistance of the Bank of St Vincent & the Grenadines.
The full moon will be the second in the month of March- the other was on the 1st. When two full moons occur in the same calendar month the second is often called a blue moon. As this is a fairly rare occurrence the phrase 'once in a blue moon' describes something rare and infrequent.
