Rangers are usually volunteers, no? My step-children's grandmother volunteer ranger patrols over near oldham somewhere up on the moors (she's been involved in all sorts, from chasing 4x4 drivers off places they shouldn't have been, to full-on rescues).
Johnny's story of stupid townies camping reminds me of the caravanners renting the field next to our mooring. First they wanted full electric hookup (they rented a field, then wanted electricity), then they left their caravans open and complained about animals getting in. What animals? The specific complaint: "Can you lock your cat up, it came into our caravan and stole a whole string of sausages!"
I really miss that cat, what a character.
