Fluctuationin NG prices, were apparently occasioned by the impending railroad strike that isn't going to happen now it seems. A strike would cripple coal transportation, resulting in using NG instead. Hence the earlier up and now the down.
All the same, I wouldn't be a bit surprised that when BIR next announces Q3 results in November they will be able to announce debt at zero. That may not lead to a divvy increase until next year, but it should give the stock a big lift. That's just mho....
