Things not to leave behind in a taxi: $500,000, 184-year-old violins on loan. The NY Post reports on one musical prodigy, Hahn-Bin, who did just that yesterday after a trip from Lincoln Center to Chinatown. He called 311, who "put him in touch with NYPD Detective Ming Lee and Taxi and Limousine Commission officials Azam Kifaieh and Sam Shady. Hahn-Bin then waited—for 15 tense hours—as the NYPD and TLC scoured GPS records to figure out which cab driver dropped him off" (though CityRoom reports it only took one hour to actually track down the instrument). The driver was contacted while off-duty at his home in New Jersey, and told them he had indeed found the instrument, which Hahn-Bin has since been reunited with. TLC Commissioner Matthew Daus declared musicians to be the most forgetful fares, saying, "There are enough instruments left in taxis to start a small orchestra." Official protocol for cabbies who find an item in their cab is to take it to the nearest police precinct "without delay."
