Yeah, I've always called pop, everyone round here does (either that or fizzy drinks). It's cool to see an American call it pop, I thought all you lot just called it soda.
Oh and just to warn you, Llangollen isn't actually pronounced Langolen, I dunno if you have been told but Ll (two L's together) is a separate letter in the Welsh alphabet that sounds pretty different. It's hard to describe in writing and you'll be able to get away with just saying it how you imagine, but you might get some smart arse who will take the piss out of you in a pub
