I was a lad of what? 10? 12? Walking home alone the four or five miles from town in a fog so thick I literally could not see my own feet. To stay on course, I slapped my sneakers as I walked on the narrow country road. When I felt the crunch of wild blueberry bushes that separated road from forest, I’d readjust until I once again heard blacktop under my feet. There were no cars – no one could drive in a Cape Cod fog like this. I knew the roads by heart, having ridden my bicycle and walked over them daily. I had no fear; conversely, I enjoyed the adventure. Home beckoned where there were lights, a fire in the fireplace, and fish on the griddle. 

Even though I walk through the darkest valley, 
    I fear no evil,
for you are with me … (Psalm 23:4)
