Exmoor seems like a possibility, but I dunno. Cliffier than I had been visualizing. Maybe there's something suitably scenic near Bristol?
I don't need to know tons about this place. Just enough to set a small scene there. Just a plausible name would do it, almost.
In exchange, I can offer advice on California state beaches and parks, including the many lovely ones on the awesome coast to the north of Sunnydale/Santa Barbara. Or I can solve a programming problem for you or something.
