Lemur's right. If you've experienced Exodus before you know it can take 3-6 hours just to reach the blacktop, then another 3-4 hours to Reno due to stacked up traffic. If I was going to try for a 12:30 PM Sunday flight I'd leave right after the Man burns...NLT midnight. Get to the airport, clean up in the lav, catch some breakfast, a preflight nap...you're golden!
Don't bore your friends with all your troubles. Tell your enemies instead, for they will delight in hearing about them.
