When Millinocket Memorial Library was on the brink of being closed forever in 2015, with the old mill city’s financial troubles, Margie King and others stepped up to raise $30,000 and volunteer to keep the doors open. Now, King’s still stepping up – literally and virtually – to benefit her beloved community institution. In between volunteer shifts at the library, helping to shelve books and staff the front desk, she’s walking around Millinocket to log miles in the first-ever Cadillac to Katahdin Virtual Run, to help raise funds for the library and 2 other nonprofits, Our Katahdin and Friends of Acadia.
