Preston's early professional career was mainstream radio (in AZ), but he moved into Christian ministry, culminating as a senior pastor in the pulpit/principal of a private Christian School. That has a way of tempering a person. My biggest beef with Preston's show is all of the blasted ads. I very often switch over to NPR in the morning when I've had enough of the ads or if what is being covered is not informative. On the drive time home, I always listen to "Marketplace" on NPR... one of the most informative and entertaining shows about money and finance to be found anywhere.
Derrel Day used to be the alternative.
