I was a wildcatter once. To say that this book is based on my own experience would be obvious rubbish. Nevertheless, many years ago, I worked for a succession of small “independent” oil companies, which explored for petroleum, competing against “majors,” meaning multinationals with vastly greater resources. Strangely, the Goliaths did not always win. There was a lot of luck in wildcatting, which originally meant hunting for oil and gas “out among the wildcats,” far from any known fields.
I had some modest success, and the money I made then helped support me when I left geology for a writing career. I met a lot of fascinating characters. I saw some of the bare-knuckle gold-rush-style towns that grew up near an important discovery.
The tie-in to this story is that people do not change. If interstellar travel ever develops along the lines I suggest, then it will surely attract the same sort of gamblers. If there are riches to be found among the stars, then wildcatters will be out there.
