Through $125,000 in donations from several private donors, including Intuit Inc. Chairman Bill Campbell, a Homestead native, the cardio room at the athletic club at the Carnegie Library of Homestead will almost double in size and get some new equipment. Donations to the library were made by the Campbell family, which includes Mr. Campbell and his wife, Roberta; as well as Ron Conway, a venture capitalist from Silicon Valley. "It's very exciting news," said Kate Grannemann, executive director of the massive building, which was donated by industrialist Andrew Carnegie in 1898.
