Problem is mate once the novalty wears off the crowds will drop. Then its down to your promotion. But like PN says, if you cannot maintain a good crowd with that side you might as well pack up.
But i have an idea, why don't the promotion give Orion a board to hang over his shoulders and walk round Swindon town centre saying please come to Swindon, and give him free entry and chuck him a bottle of water. That should do it ! But don't let him write it.
