Boating
I've spent much of my life around boats-canoes and sail boats. 
From my earliest adventures in the family rowboat....how I remember the mortification of being rescued from the houses down and, most importantly, the lesson I learned. 'Always head upwind first.' Which can be extrapolated into a life lesson...do the hardwork first.
Recently I aquired a Wenonah Solo Plus canoe...which has given me a new perspective on much of the world and vast enjoyment. The pleasure of floating down a beautiful river on a bueautiful day, sun on the waters...or the thrill of navigating a rapids...or the pleasures of canoe camping, letting you get far enough from civilization to feel apart, yet letting you carry enough of the comforts of civiliization to be really comfortable. 
I know I'm not supposed to put things like this on a 'profesional' website but this is what I really enjoy.
Since the world headquarters of HartDesign is on the mighty Hackensack, I've even composed this introduction to canoeing (or kayaking) the Hackensack River.
