LAS is only two hours by road from LAX (which is nothing in US terms)
Unlikely. Los Angeles to Las Vegas is some 300 road miles and if you have done the road journey, which I suspect you haven't, you will know that in 2 hours you are lucky to get over Cajon Pass out of the LA basin. (up which the trucks bringing your freight will be slugging up to 4,000 feet at 30 mph). Oh, and it was snowing in the pass last week !
