(Park Hills) Hundreds, maybe thousands of kids will be all over your town’s city streets Thursday evening as they trick or treat for Halloween.

Park Hills Police Chief Richard McFarland asks motorists to be extra cautious during that time.

Halloween can trace its roots back to the ancient Celtic end-of-harvest festival of Samhain.

During Samhain, people would light bonfires and wear costumes to ward off evil spirits.

In the eighth century, in an effort to spread Christianity, Pope Gregory III decreed November 1st as All Saints Day and incorporated some of the rituals of Samhain.

All Saints Day was also called All Hallows and the night before, when the traditional Samhain festival used to take place in Celtic regions, was called All Hallows’ Eve.
