California's gas is by far the highest in the country. The graph I saw just a couple weeks ago had Hawaii at a very distant second place. Jon (Slothus) found some unusually low gas out here, which is a serious exception to the norm around here. Most everything is around $3.50+ now. That same graph that I saw also showed the additional gas taxes applied by each state, and I thought CA's was still far above the rest, but I may be mistaken. I can't recall where I saw that stuff, but I'll see if I can dig it up again. But any news story (CNN, MSNBC, Fox, etc.) with "highest gas prices" always lists CA first. Hawaii was #1 last year, but we've blown by them in 2007, unfortunately.
There's actually a number of gas stations here in SoCal that are already over $4 for the Super Unleaded gas. I'm sure regular unleaded isn't too far behind, and will hit that dreaded mark in the next month or so. It's disgusting. In fact, it's so bad now that I often find myself doing calculations in my head to see if a trip is even worth it. Two books from the library: Late charge = 25 cents/day. Trip to the library (only a few miles away) = $1+ in gas. If the library's not already on the way to something else, screw it. Not worth it.
