Re: Man it's cold. This is CA, it's supposed to be warmer.
I'm a pretty big whimp when it comes to cold weather.
Then you're in the right place . . .
we hit 105F in the summer
For one day, and three days later the low overnight was probably 62 . . . You CANNOT beat So Cal weather . . . Globally!!! If anyone wants to challenge that please post a specific City

The closest I have found is Perth Australia and maybe some European Mediterranean City like Barcelona or Nice. In the case of Perth, go for it. In the case of Europe well, let's not let this get Political
5 million people within 30 miles
More like 10 Million. There's the big slam on SoCal, refer to weather comments if you are confused about the reason . . .
it takes 60 minutes to drive 5 miles on some freeways.
Maybe, but I'd suggest that is a huge exaggeration. I have been to major (and minor) cities all over the US and Globe and EVERY City has traffic issues during commute hours. We have our traffic problems for sure, but from your house you can be to the Pacific Ocean on a surfboard or have your skis on in the snow in 45 minutes . . . deserts and 10,000 ft. mountains too. Also you can be on the Colorado River in 3 hours and fly anywhere on the Planet from LAX which is also magically 45 minutes away. Add those qualifications to my weather comments and there ain't no place like home . . .
As far as smog is concerned, that has really improved over the last 40 years, but I'll give you that one. A result of the weather phenomenon again. Temperature inversion causes uniquely comfortable weather, add people and their waste to the temp inversion and voila . . . smog.
Sorry, I have to stick up for the place once in a while. It get's so beaten up. Anyone that watches the Rose Bowl gets part of the truth every year.
