I've owned several in the past. The only thing I disliked was the fact that most of them lost money. One did make me a ton of cash during its first ten years and continued to generate enough income to keep going for a total of twenty. (Not a dime left now, but them's the breaks.)
In September through December of 2008, I TRIED to launch yet another business as a water-hauling trucker. Which I was already, but as an hourly wage slave driving a company truck. The idea was to buy my OWN truck and do the same thing for the same boss. Would have tripled my gross and doubled my net.
But financing for the truck fell through, and after Barack Obama was elected President, the entire gas drilling industry in western Colorado went swiftly from boom to bust. They knew his hatred for conventional energy production, so the big companies all pulled in their horns, went into survival mode to ride out the storm.
I would have liked to have gotten that danged truck!
