All I say is OOC (Out of Control)! I just filled up at $3.06 for regular! I've seen some places here in the LA area where it's even higher...
Heck, $3.06 is pretty good now, King! I drove all over the Valley in L.A. today for a good 5 hours, and the best I saw was $3.05. Most places were in the $3.15 - $3.35 range. Even last weekend when I went up and down the Ventura/Oxnard area, the cheapest I saw was $3.05, and Oxnard is ghetto and should be cheap(er). It's gone up nearly a buck now in just the past month and a half around here. I recall filling up for "dirt cheap" in late January for about $2.35, at our favorite stop off the 5 fwy. Criminals...
And yeah, it's always annoying when I cruise out to Scottsdale to visit the folks, and see the AZ prices a good $.30 - $.50 cheaper per gallon than us here in CA. Of course, we've got some extra environmental taxes added into our prices, since there's (supposedly) special environmental additives added into the gas in California.

...(see chart).
Ah, yes. Max's chart illustrates exactly that, or at least 21 cents of it. Surprising to see a couple states back east even a little higher than us on the taxes, though their net cost per gallon is still lower.
