San Francisco gasoline prices were the nation's highest last month, averaging a record $2.17 a gallon, and officials expect prices to continue rising through July.
Gas prices in the Bay Area jumped 4 cents in May to $2.06 a gallon, according to figures released Tuesday by the California State Automobile Assn.
The high prices aren't keeping people off the road, though. About 4.2 million Californians traveled Memorial Day weekend, and 88% did so by car. That's up by 100,000 travelers from last year, according to the automobile association.
