From now until March 2010, gas prices will fluctuate very little.  In the next 6 months, we’ll see an average increase of about 20 cents per gallon.  After March 2010, we’ll see the swing be a little bit higher and a little bit lower, but through out most of the remaining 9 months of 2010, it will swing with an average in the $2.50/gal range.
