Dear Sundog, On a recent guided rafting trip down the Upper Gauley River in West Virginia, my guide was taking what seems to be a lot of extra risks. He’d always hit the hole, run the slot, even deliberately flip the boat. The rest of the customers loved it. I was terrified. I’m no expert, but I could see dozens of boats around us taking safer lines. Would I have been within my rights to tell the guide to take fewer risks—just because I thought what he was doing was unsafe?
