Big halibut, no ticket   When Ralph Vaughan left the dock on the FV Restless on Thursday morning, a derby ticket was the last thing on his mind. It should have been the first.   On a fishing trip aboard Captain Doug Judge's charter boat. Vaughan hooked a 316.6 pound halibut, the largest halibut caught so far in August, but he didn't have a derby ticket. Vaughan's son, Ted, who was standing nearby with a ticket in his pocket, came to his father's aid and struggled with the giant for nearly an hour, but the fish was hooked by the ticketless angler, so no derby reward came of the monstrous fish.   "It didn't matter to us." Ted Vaughan said of the fact that his father hadn't purchased a ticket. "We were just out there to have the fun of fishing more than anything else, it was just the fact of pulling something that big in." Reprinted Courtesy of Homer Tribune August 21st, 2002
