Once a year the National Trust for Historic Preservation announces their list of America's 11 most endangered historic places, and something in New York usually makes it on. This year that something is the John Coltrane House in Dix Hills.
The jazz musician lived with his family in a ranch house on Long Island until his death in 1967. "Today, the home where Coltrane wrote his iconic masterpiece, 'A Love Supreme' deteriorates due to lack of funds. Although a local group has taken ownership of the property and hopes to restore and interpret the site as an education center, the effort sorely needs broader attention and support."
You can its restoration by by texting “PLACES” to 25383 and donate $10, which will go towards saving historic places through National Trust outreach programs. In years past, everything from the World Trade Center site stairs to the Brooklyn Waterfront to the Lower East Side (!) have been declared endangered by the organization—but maybe they confused that last one with just be so over. It's a fine line.
