The Joslyn will be open for an after-hours, teens-only event with music, gallery tours with a haunted vibe, a selfie photo booth, pumpkin painting, designing your own decorative banner, a cookie-decorating station, and more yummy sweets and snacks. Costumes are welcome but not required (no weapon-related props, please). This free program is open to all teens (ages 13-19) from the Omaha and Council Bluffs area.
