Gross was established in 1893 by homesteader Ben Gross and his wife, who opened a general store there. In anticipation of railroad that was to be constructed, a bustling town developed and by 1904, Gross was home to multiple businesses, churches and factories, in addition to about 600 residents. However, the railroad ended up bypassing Gross, and there was an immediate exodus. A few years later, two large fires destroyed most of the businesses, prompting even more residents to leave. By 1970, only eight residents remained. Today, Mike and Mary Finnegan are the only two people who inhabit Gross, and their restaurant and bar, the Nebrask Inn, boasts about 1,600 Facebook fans — more people than Gross has seen in a century.
