I had lots of tiny plucks throughout the session and with three rudd caught at the end, that was the mystery solved.
I did get one tench though, so I was just on the right side of the line.
The heading refers to a Bob Dylan song, Slow Train Coming, which randomly came into my mind.
After I returned the fish, I searched the album of the same name and listened to it.
I actually remember buying it in the mid-eighties!
