I don't understand gas prices at all!!! In the past, prices here in our little town of 8,000 were always about 20 cents higher than along I-5 in the valley to the east, but for three months (until a couple of weeks ago), prices here were as much as 60 cents less than in the valley!!! At first, it seemed to be a price war between the two non-brand local stations (Chevron reflected valley prices plus 20 cents or so as usual). So, for three months we paid just over $3.00. Even now, prices here are lower than they are in the valley: $3.49 vs. as much as $5.99 in Portland! What's the logic behind that?
