Gas prices at Nevada pumps have hit the $3 mark for the first time in 2 and a half years. AAA Nevada reports that the average price for a gallon of regular unleaded gasoline statewide is exactly $3. That’s 8 cents more than just a week ago and 34 cents higher than the national average of $2.66 per gallon. The last time the average price of gas in Nevada reached $3 was September 2015. AAA says the highest prices are in Reno and Sparks.
