Tom Armstrong has accomplished something of which few can boast - and the ones who can are a fraction of his age. Yet the humble gentleman born in 1942 calls his achievement "no big deal" and would rather talk about his fellow Scouts than his own success. This past summer, Armstrong took part in the Boy Scouts of America's High Adventure Florida Sea Base, sailing across the Florida Keys in a 41-foot sailboat crewed by him and other Scouts under the guidance of a captain who earned his Eagle ranking as a teenager.
