A friend of mine and I will be driving to Alaska, leaving California early February and arriving in time for her new job in Fairbanks in early April. We were hoping to spend as little money as possible and are considering sleeping in the car along the way (either a truck with a shell or a Volvo). Does anyone have any advice 1. how to spend as little money as possible. 2. how to not freeze. or 3. any places that would be particularly excellent during these months.
