I've had the pleasure of meeting Michael, we're friends on Facebook, he's a neat kid. He's posted some photos from his skiing trip, and travels all over the US promoting his sponsors, mostly medical related. He enjoys hunting as well, so he's still pretty active.
He has video of one of his crashes on his webpage, every car in the race had a GoPro camera so you can see it from every angle. http://www.michaeljohnsonracing.com/
He lives here in Michigan, if you get a chance to meet him at an event do it, he'll lift your spirits because he's so positive. I think he may try one of those Chumpcar or LeMons races soon so you might even get to race against him.
