Have photos of most of the ancestral seats. I have always asked when someone was around though. People are usually really nice about it and want to know about them.
I've been nettled and scratched by brambles. I also had to walk four miles over mountain dirt tracks (and I mean dirt tracks!!) to photograph one. Every step I took in the dust and heat made me think of their journeys to get supplies, drive sheep, go to school, church, etc.
It's all been worth it.
