Motel 6 leaves a Porch Light on but ...

Leaving the porch light on, for some people, might be from the habit of keeping a light on outside their door at home for security reasons. The thinking is that a burglar will not want to be seen (by neighbors or a passing cop car) fiddling with the doorknob, and a peeping tom won't want to be seen peeking into a window. My home has outdoor lights at night for this reason.

Some campers, more likely newbie ones, don't realize that light pollution is most unwelcome when RVs are parked close together. A word spoken in kindness to 'enlighten' them will often result in a 'de-light-ful' result. ;)
