I see constant nailbiting from people involved in crude and sand transportation by rail and it's constantly over the "spread"... there is a lot of money to be made and capital needs to be spent to efficiently bring crude to market.
Anyways an article saying that towns are bracing for some imminent bust, is just a bunch of fear mongering... sure, it will happen (bust), but rapture can come at any time... let's, in the meanwhile, make some coin.
Mansions should be built with old folks in mind for bust. They can maintain the places in retirement until the boom hopefully returns.
