The cities of Norman and Noble will observe Trick or Treat night on tonight instead of Saturday due to the night OU football home game.

City officials in Moore, Lexington and Purcell have decided to stay with allowing Trick or Treat Saturday.

Some area offices are planning safe trick or treat events Friday afternoon.

The Cleveland County District Attorney's office will offer a safe trick or treating Friday afternoon. Several other courthouse offices will also be open for schools and day-care centers.

Others on the list for Friday include Rambling Oaks Assisted Living Center, 1060 Rambling Oaks Drive; 6 p.m. to 7:30 p.m.

Also Friday from 4 p.m. to 7 p.m., Marc Heitz Chevrolet, I-35 and Lindsey, will host the second annual Dog Costume Contest in the Barking Lot, the dog park located on the northwest side of the dealership.

Some dogs will be available for adoption at the event, organizers said.

Additionally, Sheriff Joe Lester announced today that he is hosting a "No Tricks All Treats" Halloween Safety Program on Saturday, at the intersection of SW 104th and S. May Ave in Oklahoma City. The program will be held from 6 to 9 p.m. and is designed to insure Halloween safety for the children who are trick-or-treating in the area neighborhoods.

"The Lake Ridge Housing Association decided that they wanted to do something proactive to deter crime in their neighborhood during this Halloween season," Lester said. "I was excited to be asked to help keep their neighborhood safer this Halloween night."

Sheriff Lester stated that residents of the Association, other concerned citizens in the area, and local law enforcement have formed a positive relationship and are working together to combat crime and dangers to children through this program. "I hope this becomes a yearly event and that it grows like wildfire to other neighborhoods. We're ready to support it" Lester said.

The event is the culmination of a month of meetings, work and interaction between residents and sheriff's deputies. A sheriff's command vehicle will be parked on site where children can come by and be given safe candy, and eleven deputies will be in the area on foot and in patrol units to insure safety for all trick-or-treaters and parents.

"My deputies are there to assist all police agencies and every citizen of Cleveland County," Lester said.
