I've got a Labor Day trip planned and will be driving from San Diego. I'll be leaving Saturday morning, Sept. 1st. I expect traffic to be heavy, but not unreasonable. I'm greatly concerned with the return trip on Monday, Sept. 3rd. I drove back on a Monday evening following a 3-day weekend many years ago and it took over 2 hours to get to Primm. I think there may have been an accident or two as contributing factors, but I'm not sure. So... Does anybody have any further experience with returning on a Monday of a 3 day weekend? I would like to wait until mid-afternoon to leave but will leave earlier if it will make a significant difference in the drive.
