Area runners and walkers are invited to “turns the lights on” for One Vision's Festival of Trees celebration at the sixth annual Lights On 5K Run/Walk. Registration is open for the Lights On 5K, scheduled to take place on Nov. 29 at 4:30 p.m. The run will start at The Other Place, 200 U.S. Highway 18, and follow streets throughout the OV neighborhood in northwest Clear Lake. Participants are encouraged to dress in holiday lights and costumes. The run is a benefit for One Vision. All proceeds from registration and donations will buy Christmas gifts for individuals supported by OV, who wouldn't otherwise have gifts under their tree. The first 100 people to register online also will receive a free gift. If temperatures fall below zero, the event will be canceled with no refunds.
