The are in every major city, so the chances of bumping into someone would be, let me get my calculator, world population minus one factorial world population times number of cities... what?? Sorry I've got Err.
So the chances are Err.
That's pretty good. I thought it would be zero.
Tbf if somebody is going to the same con as that person. Then they could meet.
It could be planned or a coincidence. But it's a way for the geeky lot to meet.
