I don't live far away and visit often. The wardens at Stanage are a plague, but the gamekeepers are worse. Had hassle from both over the years for walking with my dog not on a lead - but under close control. He doesn't chase their precious grouse (which it's OK for bankers and toffs to slaughter at this time of year), responds to whistle and hand signals to sit, return and stay, but have had long lectures from both types quoting this that and the other laws. One gamekeeper even took my photo, despite my protests. Gods know why!
They are basically ignorant jobsworth scum. If they had half a brain they'd be doing a more decent job, so I rather pity them. Ignore them. or just say "yes boss" and carry on as though they didn't exist.
