Koaher Konspiracy is the umbrella name for efforts at various and sundry science fiction conventions to get together all the observant Jews for a somewhat traditional Friday night shabbos dinner. Usually, everyone who's coming provides something, and we crowd into a hotel room for a couple of hours to eat, socialize and do Jewish things.

For reasons that can only be explained as insanity, I have been helping to organize this at Lunacon, which is NYC's only sci-fi con of note. We have had as many as 20 people for meals in the past, and it can be daunting, if fun.
