At Kidwelly Castle in south Wales, CADW have their captive Karen dragon who can and will shout abuse over great distances. Best to take off from the other side of the river and just let her rant - I swear to God one day she’ll explode.
Needless to say - these events have never resulted in the police turning up despite all the threats.
The only blue lights likely to turn up will be those of the ambulance to treat her for spontaneous combustion 
as others have already stated above - TOAL off Cadw land and “be happy - don’t worry”
