North American Science Fiction Convention

NASFiC, an abbreviation for North American Science Fiction Convention, is a science fiction convention scheduled in North America during years when a Worldcon is being held outside North America; NASFiCs are held only during such years. Bids for the location of a NASFiC are voted on by the membership of the Worldcon (or NASFiC if it exists), the year after a non-North-American Worldcon site has been selected. As of 2014, this is one year in advance of a potential NASFiC, since Worldcon sites are chosen two years in advance.
