With winter rolling around the corner, the Columbian Park Zoo in Lafayette is seeing its last week open as it closes Sunday. After this, the zoo will be closed for the winter until a yet-to-be-determined date in the spring. The zoo is open from 10 a.m. to 4:30 p.m. every day this week. The yearly "Boo at the Zoo" event will be held Oct. 16-18 and Oct. 23-25. Tickets can be purchased on the Columbian Park Zoo's website, and masks are required.
