Traffic from SoCal to LV this weekend?

[mingorama]

Just wondering if any 2+2ers have made the trip from SoCal to Las Vegas over Thanksgiving Weekend. I live in San Diego, and generally don't mind the drive, as long as traffic is tolerable. That said, I'm really unsure of how busy Hwy 15 will be tomorrow afternoon/evening. Would I be better off leaving Wednesday afternoon, Wednesday evening, or perhaps early Thanksgiving morning? (The rooms are comped, so that's not a factor)
