I see the link for KZFR in Chico, CA, which is an independant
community sponsored station which has a folk show on Wed. 3-5:30
called American Pastimes.

There is also a folk show on KCHO-www.kcho.org
sundays from 2-4 the Good Old Fashioned Folk Music Show
hosted by Lorraine Dechter. This station has a sister station
KFPR which reaches the northern part of the state.
