They are the ones that nobody knows but make sure we can walk in the night. These are the people who work when we go to sleep to protect our roads and neighborhoods without any fanfare along the way. They clean up the mess we often leave behind without us even knowing their names. These are the type of individuals who fight the battles during our forty winks. So, rest assured they are out there and if somehow you get a glimpse please make sure you thank them for all their hidden heroic works.
