After a spike last week as Hurricane Irene threatened East Coast oil refineries, Atlanta gas prices have started falling, according to a website that tracks how much we pay to fill up our tanks.  Metro Atlanta's average price early Monday of $3.65 for a gallon of regular unleaded was a penny cheaper than on Sunday, and 4 cents below the national average".

Post your discussion and answer the following questions. What have possibly caused prices to rise and then to fall?  Are there other products that may have experienced changes in prices as a result of Hurricane Irene?  Why?
