IMO, the Oil Bubble is never going to burst due to a number of reasons that are too lengthy for this post. I'm sure speculators feel the same. So NG prices are only going to escalate and SE is well positioned to take advantage. I don't know if you'll see 50 but 40 for sure by 2010.
I'm heavy in SE and DUK so a 50 percent rise would make me very happy. I'm holding and buying more.
