I may be wrong, but I'm sure I've heard in the past that for one reason or another, only FCUM are allowed to play there. Have you ever thought of posting a positive comment? Try it, you might enjoy it, you little ray of sunshine.
Interesting to read on the club website about the Quest Media link up. There are many rugby fans (both league and union) in the Tameside area and I'm sure that given the right incentives, some can be goaded through the turnstiles. RL is a cracking product and in a nice compact ground like BF, it can provoke a great atmosphere. There didn't seem to be much effort made to get new fans last time the club were in Stalybridge.
An example, there is a local free newspaper, the Stalybridge Correspondent, also the Tameside Reporter and Glossop Chronicle (don't forget Glossop, it's only a 20 minute bus ride from BF). Maybe a cut out token for a £5 adult admission or two adults and two kids for a tenner, plug it on Tameside Radio. If you get twenty in the ground on a Sunday and four or five come back, it's a result.
Just a thought...
(Oh, and get into the local schools, whole new generation of fans out there).
