Back in the mid 1960's USAC and IMCA sprint cars were real popular. There would be drivers that didn't belong to either and were good. Those drivers were called "outlaw's" originally. That and drivers who would run outside the organizations which had the name as running as an outlaw.

I remember there would be good drivers who farmed or ran a business and couldn't get away to chase points or in some cases race very often at all. But they could show up and be capable of winning.
