I usually enjoy his show, he has a lot of bluegrass artists on there and I like Dusty and Lefty. Guy cannot sing for carp, even embarrasses me when he tries to share a mic with some of his guests.
One of two NPR shows I try to catch, Car Talk being the other one.
But he won't be missed by that many people, and he is a weird looking dude. Reminds me of Michael Moore somehow.
