Many places in the United States are named for Boone, including the Daniel Boone National Forest in Kentucky and the Sheltowee Trace Trail in Tennessee. His name has long been synonymous with the American outdoors. The Boone and Crockett Club was a conservationist organization founded by Theodore Roosevelt in 1887, and the Sons of Daniel Boone was the precursor of the Boy Scouts of America. A half-dollar coin was minted in 1934 to mark the bicentennial of Boone’s birth; a commemorative stamp was issued in 1968.
