Dear Callie and NIkki,
And this goes out to ALL of my friends who took great care, and continue to take GREAT CARE, of MY GIRLS... I owe you a world of gratitude, and love, for keeping them safe and happy. Whether I was heading out to sea, exploring the seafloor in a little submersible, locked in the NR-1 nuclear submarine, diving with the whale sharks and Manta Rays, flying to Hawaii or London, or simply exploring the streets of Philadelphia, New York City, or Lancaster, PA, I always knew you were SAFE....And thought of you often.
Anything else in this world is a relatively minor detail...
