Some storm somewhere is now a Cat 1! That may cause shortages because something got prevented from going somewhere and that caused somebody to stop doing something that will lead to some emergency that will cause a shortage of everything!! So start buying everything up now or there will be nothing left!!!
Or, that is why I dumped 140 iron joes on diesel this morning immeadiately after I heard the price-per-barrel had a highest-ever price spike because of a tropical storm. Watch, prices will jump 20 cents today.
