Trick-or-Treaters, wearing every kind of costume imaginable, hit one part of Billings in force Thursday night.
The excitement centers on Clark Avenue between Division Street and 5th Street West but many join the fun, a couple blocks in all directions.
The tradition goes back more than a quarter century.
Children of all ages came out for the fun.
The exact number of people is not know, but some living on Clark say they prepared with as many as 10,000 pieces of candy.
