It can get fairly cold on the So Cal coast, no freezing or anything but it does get cold like 40 or 50 Brrrrr . Keep in mind our houses are not insulated like they are in other parts of the country.
Here is Eastern Indiana I'm seeing 2.84 (87 octane) pretty regularily. However, near Cinci I'm seeing 2.72 (87 octane). This is at a Monroe, Ohio Speedway station.
