Isle Royale backpacking: wolves howling as I got into the tent

Isle Royale backpacking, and the moment that made the whole trip was lying down for the night and hearing wolves start up somewhere across the ridge. Not one — a chorus, answering each other, going for what felt like a long time and was probably ninety seconds. The island itself is a fantastic backpacking destination: no road noise, no vehicles, moose everywhere, water on both sides of nearly every ridge. Rough notes: - Ferry logistics dictate your itinerary more than mileage does. - The trails are wetter and rootier than the mileage suggests. Waterproof footwear or accept wet feet. - Bugs in early summer are serious. Head net. - Moose are the actual hazard, not wolves. If you have been, what loop did you do? I want to go back and do a longer traverse.
