I set out at 6:00 a.m. The temperature was sixty eight degrees. The wind out of the south was cool and I felt a chill. As I descended into the creek valley, the fog got thicker. The moisture collected on every surface. The hair on my arms looked like grass collecting the early morning dew. I kept thinking that I should have worn a long sleeve jersey.

When I hit the trail, the visibility was about a quarter of a mile. As I progressed toward the river bottom, about five miles down the trail, the fog became thicker and, in places, was only about one hundred feet. There was not a lot of traffic, though, and even with the limited visibility, I was able to see oncoming cyclists as well as those who were in my lane.

I exited the trail at 36th. Back on the city streets and out of the creek bottom, the fog had melted away. I could see a wall of fog following the creek bottom as it worked its way down the the river.
