Those celebrating Halloween should remain vigilant and employ risk management procedures, such as wearing reflective gear, walking in well-lit areas and avoiding trick-or-treating alone to help ensure a positive experience. Trick-or-treating takes place from 6 to 8 p.m., in Joint Base Langley-Eustis housing areas, for children ages 12 and under. (U.S. Air Force photo illustration by Airman 1st Class Areca T.
