Have had the 08 Roadster for about a month now and we just hit our (Omaha) first night of crazy cold (low single digits). I don't have access to charging at home yet (can easily fill up at work every day and plan to have the charge-at-home straightened out shortly), so I'm soliciting any short-term advice you'd like to offer for my situation. I will ultimately be able to charge at home, and store long-term elsewhere when the weather gets REALLY bad. I'm parked inside overnight, moderately climate controlled - it could get into the upper 30s in the condo garage if it stays this cold for awhile. Thanks in advance.
