72 deg every day is just horrid
I had a German friend visit last summer. He spent a couple days in SF before he came down here. He didn't bring any warm clothes and froze is arse off Frisco. When he arrived in SoCal, I pulled out the old saw, "The coldest winter I ever had was a summer in San Francisco." To which he replied, "Mark Twain, right?"
Apparently he'd heard the phrase several times during his stay there.
