Gas prices are nearing a return to $4 per gallon as the summer driving season approaches.

The average gallon of gas in Idaho was $3.75 on Monday, according to AAA, 20 cents more than a month ago and 21 cents more than the national average of $3.54.

Boise has some of the most expensive gas in the state at $3.90 per gallon.

According to AAA, Idaho has the 10th-most expensive gas in the country.

AAA said if fuel demand calms down, the lower gas prices that are happening in other parts of the country could make their way to Idaho.
