Crash Motor GP podcast with Keith Heuwen was the best. But it's the end of the line for them. Keith announced on his Twitter than Crash GP podcast has done his last episode. One of the producers got a job in F1 or something.
But he says that he will be back with something else. I hope so. He's great.
Moto GP Mac is an alright podcast. They available as podcasts or on YouTube. They do small videos on YouTube constantly too. I like how these guys aren't politically correct at all.
