Gas to $5 per gallon by Memorial Day?

This is the current headline on the Drudge Report, and it is an important one.  Any guesses about what will happen to the "recovery" if/when fuel prices surge to $5 a gallon?  This will be a major "price point" in my estimation, where families will be hit hard enough (as in 2008) that there will be no question about the country sinking back into the Great Recession (as if we ever emerged from it in the first place).
