My wife is in California. Just arrived today.
Gasoline in her family's home town of San Pedro, south of Los Angeles, $8 / gallon.
On interstate from Barstow, CA, to Las Vegas, $12 / gallon. And that's one of the busiest thoroughfares in the nation.
If the state knocks off the state tax on gasoline, Californians could save .... oh, I don't know ... maybe 60 cents / gallon.
