In less than 24 hours, fuel prices have gone up 20cents per gallon near my house. Yesterday the local Shell had regular unleaded for $3.19. At about 3pm, it was at $3.25. By this morning it was up to $3.39. I realize that fuel prices change rapidly but 20 cents in 20 hours? Any idea what could have set off the sudden spike? Usually there is some sort of polital or natural disaster that causes such things. Did I miss something?
