Some years ago, on another site that allowed stories and posts, I was able to 'start a story.' I posted a paragraph or two, the gist of which is - Once upon a time...he went...and met...and they. (period)
I should add that I prefaced it with a request that some idle and fertile mind 'pick it up and run with a bit more.'
So someone did: "on a road trip to...and about halfway there she...and it lasted...and they almost got..."
Planes and trains and automobiles, daylight and dark, inside and outside, local-to-international, vanilla-to-OMG, it was all in there.
Anybody out there know what 'vehicle' I could use to get something like that going here?
