Automotive aftermarket for 45 years or so, currently not working ( my wife says that means I'm retired ). Think Holley, Edelbrock, Crane Cams, Hooker Headers, etc. Worked at every level, retail, warehouse distributor, manufacturer.
Served pretty much every area of the industry, street cars, hot rods, drag racing, NASCAR, local dirt stuff, OE manufacturers from motorcycles to golf carts to Detroit. Last half of my time working I transitioned into mainly purchasing and inventory management, kinda had a knack for it. Got to know some pretty cool people, some customers, chassis builders, engine builders, some people on the manufacturing and supply side. Most were pretty down to earth but there are also some really big egos.
I've said it more than once that I was fortunate that I never had to go get a real job some place.
