Anyway, it was a pleasant surprise to see we were the only ones there. In fact, we didn't see anyone else until we met a couple from New Zealand on our way back to the car. It was a really nice hike, with the dogs spending a good deal of time swimming around in the water.
As Sonja and I relaxed on the shore of Grayling Lake, watching Harvey act like a loon (click on the image to see the video):
Two Common Loons swam lazily by us, totally unperterbed by Harvey's weird behavior. Aside from a few very cold moments of frisbee recovery (shouldn't frisbees float?!?), it was a very pleasant day.
