James Osborn has just one question: "Would you drink it?" "It" being a mysterious brown sludge -- allegedly fracking fluid -- that Osborn brought in a foam cup to a public hearing in Sidney, Nebraska, in front of the state Oil and Gas Conservation Commission on Tuesday. And no, it wasn't a hypothetical question. Osborn, the first of more than 50 people to speak out Tuesday on a proposed fracking wastewater storage well in the western part of the state, chatted amiably to the commissioners as he produced three plastic cups and poured a little bottled water into each.
