I think, Derailed, that geographical location has its part to play too. If you or I live in Derry, no probs, we just toddle down to the site in the morning and do a day's work. But - notwithstanding the fact that just about enough people make the half hour or 40 minute trip to Whitehead, Downpatrick or Inchicore to keep the RPSI and DCDR going, Derry is a four hour drive for me, and for many.
Local interest is absolutely crucial in any preservation scheme. Even for necessary details like who is the key holder if the PSNI want to advise of a break in. Not much use if every involved volunteer, committed as they are, lives in Thurles, Newry or Manchester....
Local publicity and local people will save and develop the FVR. Absence of same, and the consequences will follow their unfortunate, but realistic path.
