Addition to the Michigan 100 Reinforces "Cluster" Theory

Thanks to Rick Garcia from the Historical Society of Michigan I have another addition to the list of Michigan companies over 100 years old: Eikenhout, Inc. of Grand Rapids has been providing quality building supplies since 1894.  Eikenhout increases the number of companies in Grand Rapids that have survived for over 100 years, providing further evidence that perhaps old companies do survive in "clusters."  Fully 20% of the Michigan 100 Over 100 are in the Grand Rapids area - and that doesn't count another 13 companies in nearby Holland/Zeeland!
