There probably was - and is - a better site than Falmer.................but not one that was/is available.
I think the site of the old railway works and goods depot by Brighton station would have been excellent, but there's no point in worrying over that now. It's not an option, nor, I imagine...
I can't. I never suggested I could. Like I said, I haven't lived in Sussex for years and I don't know the area. But the fact remains that Falmer wasn't and isn't ideal.
Falmer, for many reasons (transport being glaringly obviously one of them), is not ideal. Never was, never will be. Was there anywhere better? Don't know - many years since I lived in the area.
