On your way to work Friday, you may have noticed gas prices are up again.
The state average rose three cents overnight, up to $3.35 a gallon for regular.
We found prices as high as $3.49 cents in Topeka today.
A year ago the average was a whopping $.57 lower, $2.78 a gallon.
Gas prices are high because crude oil prices are up.
Spring and summer months also see a rise in prices.
Demand is up at this time and it costs more to make "summer-grade" gasoline.
