The best we saw in southern California a week ago, and the week before that, was $3.89...but California has a lot of gas taxes!
In Albuquerque a week ago, $2.89 was good. Mid-week, I found $2.85. Yesterday, $2.81!
(I would rather have it under $2 but even this is a positive trend for now. We emptied the stored cans into the Jeep and I'll refll them with $2.81 gas.)
