Conflict in the Mid-East, increased demand for holiday travel, more costly summer fuel. Whatever excuse the big oil companies are using, you can expect to pay more for gas across Michigan and wherever else you might be traveling this weekend. Around southwest Michigan the prices jumped more than $.30 from $2.77 to $3.09 during the night this past Tuesday. AAA's Fuel Gauge Report is showing the average price of regular unleaded gasoline in Michigan to be running about $2.91 per gallon. That is up about $.07 from the Michigan average at the beginning of this week.
