Warm this morning (almost 40) but very foggy the whole way in. It's bad when I can outrun my sight-line on a bicycle! I almost ran over a big chocolate lab but luckily I was going uphill, not very fast, and could go around him. I first saw him about 15 feet in front of me, scared me half to death. I can see the fog line, lights, and reflective things at least 75 feet away, but not a wet, dark brown dog. He seemed friendly. A car would have smeared him. He followed me a hundred feet or so and back into his yard, so I told him he was a good dog.
