"The Deck Grill came to the attention of barbecue champion, Joe Davidson, founder of Oklahoma Joe’s, manufacturer of world-class BBQ grills and smokers, and of Oklahoma Joe’s restaurants in Kansas City and Stillwater, and winner of more than 300 competitions. He set a contest record at the 2009 Memphis in May Championship winning five categories, Wings, Beans, Poultry, Vinegar BBQ, and Ribs.....Davidson plans to use the Deck Grill at the granddaddy of all barbecue competitions, The 31st Annual American Royal Barbecue in Kansas City, September 30th to October 3rd." Anybody here ever tried these? Are they really as easy as they say? How difficult is it to get fuel?
