What's on T. Boone Pickens' Mind?

I follow energy tycoon T. Boone Pickens on Twitter. During certain scheduled times, followers can ask Pickens questions using the hashtag #AskBoone.

Here are some of his responses to questions on various topics posted today:

On the Keystone Pipeline: “We are stupid if we don't do the Keystone Pipeline. Extremely important to our country.”

On whether he supports natural gas exports from the U.S.: “Support producers right to export but think we're crazy if we don't increase demand in US to make it unnecessary.”

On embattled Chesapeake Energy CEO Aubrey McClendon:“ Entrepreneur. Risk taker. Great company. Instrumental in the growth of natural gas supply.”

On who Mitt Romney should pick as his vice president: “Good news. Lots of good candidates to choose from.”

On what’s more difficult than making his first $1 billion: “That's a laundry list that I could say was more difficult. First billion wasn't that hard after I caught on.”
