Calvin 'Ridley' Smith talks about his earlier days as lifeguard at Boston beach. There are angels everywhere....and I don't mean the winged and haloed kind. I'm talking about the people we encounter from time to time who throw us a lifeline just as we're about to go under.Calvin 'Ridley' Smith has been one such person. As the official lifeguard at Boston beach from 1971 until June of this year, Ridley has been that lifeline for thousands of us. I for one am forever grateful he was at the beach the summer of my 12th year when a cousin and I had ventured out too deep.Ridley, who prides himself on being Jamaica's first black surfer, is also known for his calm demeanor and infectious personality.
