Not sure if "Pants" was meant as a criticism, but you were probably present when HA was born and designed, right here, and you'll recall it was an umbrella organisation in which people could do stuff themselves but under a bigger banner. It was also about prehistoric stuff alone. If you give me a salary and pay for my petrol and hotel and show me where to go and exactly where unplanned roads have been driven over and damaged officially recognised prehistoric monuments and most important of all that the issue is remotely winnable I'll go! The world is full of people damaging the cultural environment to make money, the law has deliberate gaps to let them, the best we can do is do what we can in our own tiny corner.
