Last weekend we had some ATVs on the rapidly melting trail, so I made a pair of signs (PDF, 13Kb) to mark it. I have my doubts as to whether these will have the desired effect, but I don’t really want to block the trail to all users, and this should be sufficient.
The signs read:
They’re just paper stapled to plywood, so eventually we’ll need to get something more weather proof. Maybe black text printed onto acetate, with a florescent file folder stapled underneath? Unfortunately, I have a feeling the most likely form of damage will come from humans, rather than the elements.
