Wills not rahey? Hmmm....I would say that Wills does have a LOT of rahs but they seem to clump together from my experience, making them less obvious. Even just going on the 'Wills bus' to town on a Friday night shows how patently clear that there ARE a lot of rahs there; I still maintain that 'chants' on the bus are a result of public schooling.
I would also like to say that the Wills rahs are more inclusive perhaps? They don't go out of their way to annoy you but you cannot deny that they are not there. You've got frickin' Jack Wills 'tracky bums' on sale (I DETEST that phrase), what says more rah than that? Furthermore, there is an attitude up there (particularly at the start of the yeah) that being 'up on the hill' is way better than being down at '***** Bunker', especially when people endlessly bring up formals and the like.
I just think that even though I know a few people well from Wills that aren't rahs, there are a lot of them there. You just have to look around!
