Love Shaddox!

Really enjoy having this podcast queued up. Dr. Shaddox does a great job of sharing his knowledge (especially with a trained monkey like myself) while still holding my attention.

I want to like this podcast.

Travis speaks like a true professor. Dull and monotone. His sentences start off normal and then he eventually ends them mumbling in a low voice. Maybe it’s just me, but if there is any background noise I can’t understand half of what he’s saying. Grab a good pair of isolation headphones. You’ll need them.
