Filling up your gas tank may be easier on your wallet as we continue into 2013.

According to AAA, fuel prices are down substantially from where they were back in September. A few months ago, unleaded gas across Nebraska averaged $3.90. AAA says prices have dropped for a number of reasons, including crude oil prices which continue to hold steady at $90 a barrel.

Jared Smedley and his family are traveling across the Midwest and he says they keep seeing gas prices get lower as they drive.

"We've noticed anywhere from $3.45 to $2.55 and we just filled up like 20 miles before seeing the $2.55 so we missed out," said Smedley.

AAA says another reason for lower prices is the building of U.S. crude oil inventories. North Dakota has become the 2nd largest oil producing state in the county, surpassing Alaska and California. U.S. crude oil inventories are currently 13% higher than they were the same time time last year.
