I am going to be in Vegas for a couple of weeks in January for a work conference. While most are complaining that it is winter, I couldn't be happier about it as I can have a quick ski before heading home to Aus. I was thinking of renting a car and driving from Vegas to Mammoth or Tahoe for a few days. I have searched through these forums and both areas get good reviews, so the decision is really about which will be easiest, as I will be driving on my own.
Thanks for your help
