I live in Southern California, the temperatures here are pretty laughable when compared to other places. I am planning on getting a sleeping bag and am deciding what temp rating to get.
Realistically in the next 5 years or so I expect to see temperatures of around 0-15 degrees at the lowest. Within the next year probably not even below 40. In fact the vast majority of my backpacking will be done during either blazing temperatures or what most people would refer to as warm weather.
I feel getting say a 15 degree bag would be a mistake for me, as I've heard many tales about unzipped, feet out, only half on the person, but sweating to death from people with 0-15 degree bags.
I plan on purchasing a 40 degree bag and a liner, this way I figure I can COMFORTABLY take anything down to 25 degrees. I plan on buying another bag between 0 and 15 degrees later on when I get into the cold weather stuff (traveling, really). I was wondering if this sounded like a good idea or a bad one.
I also tend to sleep extremely hot.
