since I'm commuting a lot and aviation related content is rare on the
air, I got used to listening podcasts while in the car.
Starting with Jason Miller's great "The Finer Points" I'm now looking
for more sources, especially related to IFR flying and other "advanced"
topics.
Are there any recommendations you have?
