What might be the scariest part of Dublin's Halloween Spooktacular event that will run from 3 to 8 p.m. Oct. 18 in Coffman Park?

The answer is the prospect of not getting a Trunk or Treat Trail ticket before they are all gone.

The Trunk or Treat Trail in the north meadow of Coffman Park east of the Dublin Community Recreation Center is an opportunity for 4,000-plus children to go trick-or-treating along a lineup of more than 30 Dublin businesses and organizations.

Other Spooktacular activities -- which do not require a ticket -- will also be held in the north meadow and the recreation center.

They include crafts at the Cardboard Creations area, hayrides, a Haunted Trail, superheros and princesses in Character Camp, the Bug Man and Turtle Lady, a hay-bale maze, strolling stilt-walkers and the Boo Boogie and Hip Hop Halloween music and dance performances.

Food vendors will be on site, and other activities also are planned, event organizers said.

Trunk or Treat tickets typically are all gone by the beginning of each Spooktacular, so families are encouraged to pick up their tickets in advance, said Sara O'Malley, a Dublin events specialist.

Dublin residents, city staff and Dublin City School District residents can pick up the free tickets for children participating in the Trunk or Treat Trail beginning a 8 a.m. Saturday, Oct. 13, in the Dublin Community Recreation Center, 5600 Post Road, O'Malley said.

Ticket distribution -- while supplies last -- will continue during the rec center's regular operating hours until 1 p.m. Oct. 18.

Proof of residency, such as a driver's license or utility bill, is required. There is a limit of five tickets per household. Tickets are not required for adults and infants.

Tickets are available in 15-minute increments. The first group of 200 trick-or-treaters will start at 3 p.m. and the last at 7:45 p.m.

Those with tickets will be allowed to enter the Trunk or Treat Trail only during their ticket's 15-minute period.

Tickets will not be accepted before the time printed and will be accepted after that time only if there is not a line waiting to traverse the trail.

If any tickets remain prior to the start of the event, they will be distributed beginning at 2 p.m. at the information tent in Coffman Park. Tickets will not be replaced if lost, event organizers said.

Spooktacular parking will be available in the southwest parking lot of the park and attendees can take the hay ride from the lot over the bridge to the stone pavilion in the north meadow of Coffman Park, O'Malley said.

This year's event will not feature a king and queen of Halloween, O'Malley said.

The city decided to skip the tradition this year but may resume it next year, said Christine Nardecchia, Dublin Director of Volunteer Resources.

If severe, threatening weather is forecast the day of the event, the Spooktacular will be canceled. If it is raining, the event will be held.

If threatening weather is expected, city officials would determine whether to cancel the event by noon Oct. 18 and post notification on the city's website and social-media accounts, O'Malley said.

Weather tends to determine the event's popularity, O'Malley said, with attendance ranging from 4,000 to 8,000 people in previous years.

COSI will host science stations inside the rec center, O'Malley said. Also inside will be the Character Camp.

Families can take Halloween and fall season portraits inside the rec center's senior lounge area.

Returning activities include the "merry, not scary" Haunted Trail in the wooded area between the rec center and the north meadow and the Cardboard Creation station, where kids can use their imagination to make spaceships, fairy houses and more.
