Manage a 15-man crew in the utility industry - low 60's
In my spare time I could best be described as a venture capitalist I suppose. I scout a market for a potential profitable business opportunity. Invest capital in the start-up, build a customer base, etc. Once said business is profitable...I sell it.

Yeah I know, weird, but I'm not the type to run a business forever. There's always a new idea to explore! - avg. over last 10 years has been about $50k/year.
It also helps that the wife is now a manager in the finance industry pulling low 60's as well.
