Apart from me, since I live with one But yes, I see them up on the mountain here a lot. There was a little band of greys in Abergwyngregyn too when I was on a dig there last year, I think they're a pretty much permanent fixture since they mug the tourists on the path up to the falls (they're quite section A like tho). Conwy mountain's another good place to see then, if you park up on Sychnant pass and have a potter around the mountain there.
My son's supposed to be photographing them for his A level project so I'll get him to post some of the pics when he's finally well enough to be allowed to go up onto the mountain!
Mmmm bloomin vandals the lot of em lol !!!! my poor OH was walking back in the dark with the dog from the top of the pass, as he approached the car and due to the lack of light he could just make out what he though were a group pf people surrounding the car, it wasn't until he got a bit closer he realised it was infact 6 of the hairy little buggers trying to jimmy the car open, they didn't even have the decency to look bothered when he and large hairy dog got closer and he had to make loud shooing noises to actually be able to get in the car. I think that this little group is fairly permanent up on the Sychnant pass as quite often on the way home from work they are playing chicken with cars as you drive along. I do know that at least one registered and very nicely bred section a stallion was added to the Penmaenmawr herd a couple of years ago, so there may be a few more refined babys and youngsters up there now.
