Plan a trip along rt-70 in mid Nov., have a 2000 van. I wonder whether there will be some cars on the road between Kansas & las Vegas(say at least 1 car passing every 2-5 minutes during day time). And how's the road condition? Mountain and desert road between kansas & LA? Hope not much snow/storm during that time. We already got the tour guides and maps from AAA and assume can drive 70 mile/hour most of the time, for 2800 miles we need to drive 6-7 hour each day. Is this realistic? Or we should leave more time for Denver - Las Vegas trip as this is little bit desert/mountain road? Any info would be very helpful and thanks a lot.
