Well that's so stupid I'll not bother to reply. I hate futile bloody signs that do nothing but antagonise. In my local wood there was no vandalism until busybody bureaucrats stuck up signs saying don't do this that and the other. The ones that haven't been torn down are riddled with air gun pellets.

If you want to get things in perspective Oh great and mighty Four Windbags get a look at this

"the Druid's
Temple near Ulverston had been vandalised - the tallest stone in the
inner ring had had red paint poured over it."
