I'm a professional geologist, an explorationist for oil. That's what I've done in my career, one that's culminated in - at least to this point - playing a part in finding the largest field in the last 40 years anywhere in the world. That's the Bakken field, which I believe will yield 24 billion barrels of oil in the decades to come, maybe more.
It's harder, but we're still finding oil in Oklahoma today. The bar has been raised on startup companies, but it can still be done. Every regulation and every rule limits you, but, yes, it can still be done. That's the beauty of living in a free country and having the freedom to have an idea and become an entrepreneur.
