Going to Las Vegas to watch the Endurocross in November. Anyway got a car for three of us with a one way rental from LAX to LAS. I know we could just fly over for $49 but wanted to try a road trip. I have done this trip a few times before however this time we will be arriving around 4pm on a Tuesday. I'm sure the traffic will be bad in LA. What time does the traffic slow down. We were going to try to make it to Primm and stay there for the night. But may consider doing a little traveling either to Arizona or Reno on the way to Vegas. Any ideas? Open to all ideas/routes.
