Call for news on gas supplies, prices

Just fanning out to see if anyone has any solid, substantiated news about gasoline supplies to Tennessee and Kentucky (basically, Southern states) today and over the next few days. The last thing I've seen was in the Houston Chronicle, of all places, that two major pipelines were blocked off; I also heard anecdotally, this afternoon, in east Tennessee, that gas supplies are short, people are waiting in line at gas stations, and prices are up to $3 a gallon.

My sister is driving here tomorrow and I wanted to know what her driving problems might be. Thanks for any help at all, links, etc.
