I wouldn't mind seeing a bumper sticker that just said 'APUG: Analog Photography Users Group'.
Or a play of the X-files... "The Film is out There". Something to tell people that film is still alive and kicking. Something with some meat... some substance, something that actually makes people scratch their head and wonder about that funny old stuff they used to load into their cameras (that are undoubtedly sitting in their closet, perfectly functioning).
I don't know, I think that with our powers combined, we could come up with a really good, original and thought provoking tag-line.
In the meantime, I'll keep thinking...
