Don't be surprised if you see several of the Halloweeners in this photo series ringing your doorbell this week. Here's our second section of photos from Tuesday's ONU Residential Life drive-thru trick-or-treat event on campus. The drive-thru drew an estimated 300-plus people in 75 vehicles, according to Isaiah Bailey, event coordinator. Ada's trick-or-treat is from 5:30 to 7:30 p.m., Thursday, Oct. 29.
