Why? Look at Wimbledon struggling now in league 2, with gates we would not achieve, the cost of being a league club is massive, so much more so than the Conference Prem, just the admin, the security measures/stewarding, not to mention the costs of upgrading the stadium with digital turnstiles, CCTV, Police control room, holding cells, larger dressing rooms for bigger squads, disabled facilities, female official changing rooms, it is a massive expenditure.
I'd love to see Alty in the league, I really would and thought back in the 70s and 80s that I would do one day, I just think that our chance was then, the game is different now and it is much harder to get fans to follow small teams thanks to Mr Murdoch.
