Yep Bill, I know of that thread but thanks. Hope I'm not boring you too much with this and I'd had a few to drink last night but... I think Skerryvore road starts at what called "the green", really only a triangle where a few roads join. By that way of thinking, Old Swan is the first house. Skerryvore Road joins Frith road at some point but in places like that, you know the house names more than road names. From Swan, if you found it, you would come to a sharp bend with a right hand turn that is a private/non maintained road and leads to Goedlodd woods. Skerryvore is just before there.

Anyway, not to worry, it's quite remarkable that someone in the US can just home in on Skerryvore Road without looking further.
