People are topping off out of panick and that's what will cause a shortage...This will be a problem if people don't chill out quick!
Some places it is panic. Here in Austin I think it is more of a "get before it goes up higher" mode. I don't get the sense here that most folks in this area think we are on the verge of running out. They just don't want to pay higher prices. Whereas in other places they might really be running out.
