The City of Lawrence is asking for more volunteers to help with its annual Halloween trick-or-treat event at Prairie Park Nature Center.

The event, with the theme Enchanted Forest, will be held at the nature center, 2730 Harper St., from 1 p.m. to 4 p.m. on Sunday, Oct. 25.

The city needs volunteers to take admission, serve refreshments, paint faces and be in costume along the nature trail.
