PIERRE, S.D.(WNAX)- Gas prices are rising and that has caught a lot of attention.

Shawn Steward with Triple “A” South Dakota says we don’t normally see prices going up this time of year.

Steward says crude oil prices have risen rapidly.

Steward says the cost of crude oil relates most directly to gas prices.

Triple “A” reports the national average for a gallon of gas at three forty-eight, with the South Dakota average at three thirty five.
