It's invaluable, because they can see for themselves what's really happening. When they closed the building.... I was in that building a week before that and I couldn't see what was being discussed or stated as the problem. Yes, there were things that had to be fixed but, quite frankly, for whatever reason, the decision was to close the building.
I think by having a minister see the site hands-on, understand the problem and understand the solution, you can make an appropriate decision.
