Grab your clubs and perfect that drive because Guinness & Co. is searching for the ultimate golf foursome to play with Irish pro golfer and 2010 U.S. Open winner, Graeme McDowell, in the first-ever GUINNESS Black 9 Challenge. We stopped by Chelsea Piers this week to hit a few shots with Graeme and get some pics. Between now and June 30th, U.S. residents of legal drinking age can visit http://www.Facebook.com/GuinnessUs where they can describe, in detail, who would be included in their ultimate golf foursomes. Based on the originality and creativity of the entries, Graeme McDowell, along with a panel of judges, will award the winners and their golf foursomes with all-expenses paid trips to Chicago in September 2012. While there, they will tee off with McDowell — and face some unusual challenges on the back 9 — all while responsibly enjoying the flavorful taste of GUINNESS Black Lager.
