Interesting. I live on the West coast and I cannot remember the fall foliage ever being as spectacular as it has been this year. I was just wondering the other day why it was so much better than ever before.
Summer is when the jet stream is to the north, and we get included in the band of warm air that California always enjoys. Winter is when it moves to the south, putting the Seattle area in the cold band that Alaska always endures.
The jet stream is late this year.
Sell also Scrubs, filmed in LA but set in "San Frangeles" although never admitted in the script. They wanted to avoid the LA/SF/NY trend of mentioning place names and expecting the whole world to know what you are talking about. For the longest time I thought scrubs was set in Florida.
