I was riding my mountain bike down a steep remote logging road. I came around a corner and a wolf was sitting in the middle, howling it's head off. There was no way I could stop, so with a death grip on the handle bars, I tilted my head back and gave out a loud howl myself. The wolf spun around and went into a crouch. It curled back its lips and snarled. When it realized what was happening it sprang into the forest. Totally shocked, I laughed deliriously for a mile down the road. What an awesome adventure.
