It's one of my semi-regular walks, but I hadn't taken it in a while, so I noticed how pine boughs crowd the sidewalk, how fast cars speed along beside the path, how close together are road and sidewalk.
How exposed I suddenly felt! For after all, what is a mere walker when confronted with tons of speeding steel?
(I realize I don't take too many photos of cars on highways. I'm much more likely to snap bucolic shots like the one above.)
