To be fair, I would doubt that there are many current Bulls fans from Halifax. I think they maybe picked up about a thousand in their Glory Days but as they are now back down to the hard core I would suggest that they are now mainly from Bradford.
Apart from my mate at work who is a lifelong Bulls supporter and lives at Southowram but he claims that he was born and bred in Bradford and I can't imagine anyone saying that were it not true! lol
