Born and raised at Kunia Camp in the '50s and '60s.  Most people knew one another.  No need lock car doors or house doors.  You didn't hear about homes getting broken in to or cars stolen.  You didn't hear about drugs.  Kunia Store with 2 gas pumps, and Post Office inside.  Cash your paycheck at the PO.  Most residents "charge" on their store account. 
About twice a week a Japanese man and his wife drive their converted bus with groceries, household goods, etc., comes in and makes several stops in the Camp and residents would buy what they need.  Us kids would take a break from playing marbles, spinning tops and buy candy and ice cream.  
Manapua man, ice cream truck and an old green truck with fabric material would make its rounds also.
If I remember correctly, the pau hana horn would sound off at 3:30 p.m. , and the night shift would begin.  Those were da days...
