I feel a chill just looking at that picture. I was born and raised in Southern California and feel really cold if it drops below 60 degrees. We carry a little self contained propane heater with us to use at events, put up a shelter in the rain, and generally run for the car if it drops below 40 degrees.
Wa Wa Wa Wimpy! but can not help it.
The only way I could enjoy taking that picture is with a remote trigger from my heated automobile. Now that I think of it WiFi and an iPad with that total control app might be just the ticket. That and some kind of remote controlled servo kit to swing the camera around for panos.
