Off topic to this post, I guess, but someone mentioned flat-bottomed drag boat racing. Good friend of my dad still holds records in a class or two, 158 mph on the water, in the Master Blaster. Story goes, they stopped running those particular open cockpit classes because they were so damned dangerous. THis is what a guy does that gets burned out with flying, motorcycle racing, drag racing, and everything else that's boring because PTSD is a bitch. His HD dealership was a freaking playground, to boot. Bikes, hot rods, drag cars, airplanes, drag boats, engines, engines, more engines, guns, place was almost too much for my 8 year old brain to handle. Aside from my pops, the guy was my hero when I grew up.
