Although I've had the pleasure of many flyfishing trips for trout and salmon with son-in-law Edward Zak, DVM, and his father (both experts), grandsons Ben and Darren aren't fisherman; but three summers ago the three of us had a good adventure. Unseasonable late summer rains had raised the water level of Pine Creek; the picturesque stream that flows down the famous Grand Canyon of Pennsylvania. We decided to take the half-day rubber raft trip downstream through the canyon, something none of us had ever done. Usually the expedition is done with more than one raft, for mutual safety, but we were alone since it was off-season. We could have had a guide, but we decided we couldn't get lost. The proprietor warned us not to let our feet hang over and get caught between rocks - some of his former clients had been drowned that way in the fast current. He also told us that going ashore could be dangerous because of plentiful rattlesnakes. My main concern was that we might let the raft get away from us, and have to walk the rest of the way down the rocky snake-infested gorge. It was an exciting ride. We cautiously went ashore to eat our lunch. The raft was leaky, but the day was warm enough that the water didn't bother us. The boys, real water rats from their life on the Outer Banks of North Carolina, were real good sports and want to do it again!
