Gas prices are continuing their post-Labor Day decline. Analysts say it’s a result of lower oil prices and less demand with summer over. The Energy Department reports the average price of regular unleaded came down another 5 cents nationwide in the past week to 3-24 a gallon. 59 cents a gallon less than at this time last year. Except in California where prices have gone up 4 cents because of some refinery problems. According to Triple-A, gas is averaging 4.89 a gallon in San Luis Obispo County and 4.70 a gallon in Santa Barbara County.
