So the promoter was left trying to promote a show with no vendors participating. Faced with the prospect of a handful of show attendees walking up and down rows of empty tables, they called it off.
Actually, I was being sarcastic about the use of the phrase “assault weapons”.
An “assault rifle” is a select-fire rifle capable of firing multiple rounds with one trigger pull,
as opposed to a “modern sporting rifle” that is self-loading, magazine fed, and fires one round per trigger pull.
I don’t think there were actually many actual “assault weapons” for sale.
