A great exploration of our limitations has just popped up on YT on Paul Whitewick’s excellent channel: ‘The 5000 UK Monuments Off-limits to the Public’. TMA gets a mention. Those TMAers who go for wanders have doubtless found sites that are unrecorded. That 5000 figure is I’m sure a huge underestimate. What to do if you chance upon these when you’re not supposed to be there?
