Of course "there are locations," there are always locations. It's hard to be an oil derrick worker in the middle of Manhattan, and that's not because the cost of living there is so high.
That's been my point all along. There are always going to be locations where the beer flows like wine. But that isn't everywhere.
New York state or New Jersey versus North Dakota right now might be a better analogy than Manhattan for a wildcatter. Sure, there are probably wells in NY and NJ, but the big money is in ND.
