I've said it a few times and for land's sake I mean it. You need a good light when out trick or treating. It's just the right thing to do. There's this weird paradox in which driving a car on Halloween night makes the driver unable to see people not normally in the street dressed as Power Rangers. All caution is to the wind and the only thing keeping you safe is a good light.
Fortunately Burger King is here with free flashlights and treat bags to use when you go trick or treating. Assuming the manager didn't take them all home. In all honesty, that's a pretty great freebie for a fast food place. Those are the type of flashlights normally sold at stores. Not too shabby Burger King! You might recognize it as the old flashlight your grandmother keeps by her bed.
So take your flashlight and be safe out there. Later, your parents will happily take your new flashlight and keep it by their bed. Another word of advice, wait until it's night time to use your flashlight. That damn kid's going to run out the battery before sunset.
