The spook-tacular 29th annual Halloween Warmup will be a wicked good time for children ages 4 to 11 today and Saturday.

A group of about 25 people will be led through the Jay C. Hormel Nature Center woods every 10 minutes to meet assorted spirits. The event is co-sponsored by the Matchbox Children’s Theatre.

The first hike is at 6:50 p.m., and the last hike is 9:10 p.m. each day. Cost is $6 per person, which includes apple cider and a cookie. Tickets are available at Super Fresh, 2104 Fourth St. NW. For more information, call the Nature Center at 507-437-7519.
