Tennessee

My uncle was one of those who worked for the TVA at its begining.

My f.i.l. worked for the CCC (Civilian Conservation Corps) in middle TN which was FDR's first New Deal agencies. Jobs were very scarce during the Great Depression.

Folks can visit most any state or National Park in U.S. and you'll be driving on roads, walking on trails and using facilities built by the CCC.

For a fascinating read, check out this CCC on Wikipedia.
Here's a few of the famous folks who joined:
Alvin C. York
Hubert D. Humphreys
Raymond Burr
Archie Moore, Boxing Champion
Robert Mitchum
Chuck Yeager
Stan Musial
Walter Matthau
