(UNDATED) - Say hello to $4 a gallon gas in northeast Indiana. Prices spiked by almost a quarter on Wednesday which means grumbling motorists are now paying $3.99 a gallon for regular no lead. The spike even surprised those at www.gasbuddy.com. They reported on their Twitter account that only Indiana prices spiked on Wednesday and there were no changes for the day in Michigan and Ohio prices. But with wholesale prices going up by 5 1/2 cents a gallon on Wednesday, residents in those states will likely see a gas spike in the next day or two. The web site www.indianagasprices.com reported the average price in Indiana was $3.85 a gallon. Several stations including those in Goshen, South Bend, Plymouth, Indianapolis and Lafayette were selling gas for $3.99. Shelbyville had the highest gas price in Indiana at $4.49 a gallon. The lowest price was $3.57 in East Chicago and Hammond. It's been almost a year since gas prices have been this high. You may recall prices jumped to $4.29 a gallon in early June of last year before they dropped sharply.
