Well it was already a big ready-made hole in the ground, so no excavation, and it was an eyesore that needed tidying up, so putting a football ground there seemed ideal. However it only took a few seconds of consideration to realise that it was totally unsuitable. The site would have cost millions to clear (as it's riddled with asbestos), before we even started building. There is virtually no access as it's only served by a single country lane and a dismantled railway. Rebuilding the railway (nearly four miles not a few hundred yards) would have added even more - plus the ongoing maintenance as it would be the football club's private branch used only on match days. That's before you got the difficulty of running a matchday service with all the fans going one-way. (Where would they change to separate between East and West?)
You say you were viewing it from afar so you probably didn't realise the problems. FPC etc were relying on people like you to say "Hey that sounds good!"so they could muddy the waters. Believe me no fully sentient person in Sussex thought it was remotely feasible.
Ancient history as you say, but re-reading this thread makes me remember just how much effort we had to put in to getting the stadium. It was battle after battle after battle, and actually I don't think it should be forgotten.
The line from the cement works to the junction with the coast line is two and a half miles, not four miles. And the road is not a "country lane" it's the A283. Facts, dear boy, facts!
