I agree. Like I say I'm relatively new to it all really. It's only the past year or so I've took more of an interest. It really is like looking into another world.
It saddens me too when you think of what these places used to be about and now no one (general public) really cares. I find it all fascinating and it adds something else to my walks in the great outdoors.
If I can find the time and money, I'd like to do other similar videos. If only so the uninitiated can be introduced to the subject.
I'm thinking of doing a video of Five Wells chambered tomb in the Peak District next. It affords nice views (great backdrop) too. Even that place makes me cock an eyebrow when I think we shouldn't even be seeing the tomb - it should be found buried ;)
