As a railfan myself, I second Jerseyman’s opinion on the restoration. Being true to the original paint scheme is always preferable in the mind of most railfans and since freight cars from virtually any railroad could have passed through Pemberton there is nothing unrealistic about it being there. And as Jerseyman implied, it would sure be a break from all that PRR Brunswick Green and Tuscan Red. I realize that it's easy to voice an opinion when it's not your sweat and $ going into the project, and I do applaud the efforts of everyone involved, but at least my $0.02 brings it up to $0.04!
As a side note, I really need to stop by and see your work first hand. I only have the ability to financially support so many organizations, but when I see a small group like yours actually making real progress it makes me more willing to offer what I can, membership or otherwise.
