Recognizing Kalaupapa’s one-woman post office as a “lifeline” to the community there, the U.S. Postal Service has decided to spare it from closure. 

The tiny office serves less than 100 residents and was on a list of thousands of locations nationwide that are being considered for closure, Hawaii News Now reports.

The former leprosy settlement is accessible only by mule or plane. Residents there worried that losing the post office would cut them off from communication in an area that already has no Internet or cell phone access.
