With Car Talk coming up on 25 years running, Click and Clack have decided to retire. They'll continue broadcasting new shows until October, and then after that, it'll be reruns/best of shows. It's weird to think that, for all but 4 years of my life, these guys have been hosting a great radio show. I think it's one of the few that could have survived on regular radio, and one of the few shows on NPR that have allowed it to stay on air (well, other than government funding, but that's a topic for someone else to cover.
I've always enjoyed their show, and I will miss not having new episodes to look forward to in the future.
