We will be heading from Australia to San Diego on 18th Febuary. We will be in the US for 3 weeks. I'm thinking about a week somewhere skiing. Any suggestions? I hear there isn't much snow over there this year, right? Maybe Mammoth? Could we drive there from San Diego or would we need to fly or are there other options that will have snow? We are all low intermediate skiers with children ages 7,8,10 and 12. Any advice or suggestions would be welcome.
