The Friends of Union Fair plans to sponsor its sixth annual Halloween Trail of Terror on the last three Fridays and Saturdays of October (Oct. 15, 16, 22, 23, 29 and 30).

The trail offers an after-dark, outdoors, walking event through the barns and around the grounds of the Union Fairground, from 6:30 to 8:30 p.m. at 150 Fairgrounds Lane in Union.

The cost will be $10 per person, cash only. Refreshments will be available, courtesy of the Warren Odd Fellows, with proceeds going to various charities.

This event is recommended for adults and children 12 and older. Younger children must be escorted by an adult.
