CLAY COUNTY – Sweet tooth junkies, freaks of frights and costume zealots can unite at any one of several Halloween-themed events.

Four of the largest events will be the Boo on the Boulevard parade and treats along Lawrence Boulevard in Keystone Heights. First up are Tales from the Clink at the Historic Triangle in Green Cove Springs, the Green Cove Springs Police Department’s Trunk-or-Treat on Oct. 23 from 6-9 p.m., and the Clay County Sheriff’s Office Trunk-or-Treat on Oct. 29 from 6-9 p.m. Several thousand Ghoulish revelers are expected to attend the three, and the GCSPD Trunk-or-Treat, also from 6-9 p.m., at the Chief Derek S. Asdot Memorial Building at the police department, 1001 Idlewild Ave.

Every trunk spot has been reserved, and there is contest for the best decorated trunk and for the best costume. The event is free, and most of the businesses and organizations distributing candy will be dressed in ghostly Halloween affair.

Last year’s Trunk-or-Treat attracted more than 4,000 guests, the department said.

That will be followed on Friday, Oct. 30, with Tales from the Clink from 5-8 p.m. at the Historic Triangle, 915 Walnut St., in Green Cove Springs.

Presented by the Clay County Clerk of Courts and Comptroller Tara Green and the Clay County District Schools, the event includes a recreation of the Sweetheart Slayer murder trial at 5:45 p.m. and 6:45 p.m. at the 1890 Old Courthouse, tours of the Old Jail with actors from Ridgeview High representing infamous prisoners, the museum, train station, concessions and exhibits from the school district, Clay County Archives Office, History Museum, Parks and Recreation, library and Village Improvement Association.

Admission (cash only) is $3 for adults and $1 for children.

The Big Four will wrap up the next night with Boo on the Boulevard on Oct. 31 from 6-9 p.m. along S. Lawrence Boulevard, from S.E. Lakeview to Flamingo Drive, in Keystone Heights.

The family-friendly Halloween celebration features street closure for safe trick-or-treating with food trucks at City Hall, live music from PNC Bank and Second Chance, a festive photo booth, games and candy stations hosted by local businesses and civic organizations.

The free event is sponsored by the City of Keystone Heights and Clay County Tourism.
