Lee grew up loving life outdoors in the small town of Alva, FL. He was always on a bike, using it for transportation as well as recreation. He continues that tradition today as a bike commuter and avid recreational cyclist. He has ridden across the state of Florida in a single 170 mile ride as well as raced in numerous triathlons.
