I'm going back a few years now (for a change !!
) to the 1997/98 season to be precise, and we did actually do some kind of advertising campaign up at Lancaster Uni because I can well remember a group of around 10 or so lads who used to come to EVERY game.
Ok, their group was small (one of the lads I remember was an Irish lad, well sound he was), but my point is that they ALL purchased scarves and shirts etc, they all drank before and after the match in JB's Bar, and they also joined in the vocal support in a big way too (I wonder where these lads are in life now?)
Point being, a campaign at the Uni did work (albeit in a small way), I think Shrimper may have had something to do with it, and it can work again.
ie, to entice them in, present your NUS card at the turnstile and get a pound or two off your admitance cost.
