Neal Boortz and Free Talk Live are, in my opinion, two very good talk radio shows. While both are very different (Free Talk Live is much edgier than Boortz), they both succeed in talking about libertarian concepts in ways that make them easy to understand.
Call your radio station and ask for them to run these programs in Indiana. More importantly, advertise on these stations when these shows are run, if you are able to do so.
Free Talk Live is currently on WXNT 1430 AM in Indianapolis on Saturdays from 7-10 pm.
Boortz is on the following Indiana radio stations:
WCSI-AM 1010 Monday through Friday 9 am - 12 noon.
WXNT-AM 1430 Monday through Friday 10 am - 1 pm; Saturdays and Sundays 6 - 8 am.
WRAY-AM 1250 Monday through Friday 9 - 11 am.
