I race every Wednesday at the Annapolis Yacht Club series and I usually do two or three Chesapeake Bay one or two day races a year. I'd LOVE to eventually do some offshore racing - I'm jealous!
Used to play rugby when I was younger (age 22 - 32) and played football, wrestling and lacrosse in HS.
Competition is a VERY important part of life, IMHO. Good thread idea, OP.
