I'm with Linnet71 on the subject of gates. I'd say that a good few will inevitably drift off if we're not challenging at the top. League standards aside, people have got used to a team that wins the majority of its games over the last two years. It's easy for people to get carried away and some may find the step up in standards a shock to the system.
From more recent experiences such as the two years in the DM Eastern and the subsequent four in the Southern Premier, there were only ever a small minority of clubs that brought away fans to The Walks, and certainly never enough to significantly swell the attendance figures.
