Put up ‘Wanted’ posters up showing a photo of the logs blocking trails and a picture of a crash victim, preferably a small child. Reward for information leading to the identification and possible prosecution of this individual.
I was putting the second one of these up in Lordswood a few years ago when a harmless looking woman with a couple of Labradors asked what I was doing. I explained about the danger that this person was creating and that after reporting it to the police they had suggested I get the persons identified. She went a bit white and said it was a fuss about nothing but was sure it wouldn’t continue. Denied it was her but the trails were log free for a while.
Started again since then though. Normally dog walkers who don’t like bikes riding through THEIR DOGS toilet.
