Funnier than he thinks he is.
once drove Vegas to La. Left Veags in 96 degrees and arrived to something similar in LA, in between went through snow drifts!The coach trip I went on from LV to the Grand Canyon included the Hoover Dam automatically.
From LA to Vegas I got the bus. It was fairly long (but obvs was city centre to city centre) but also fairly comfortable and the views were interesting in a weird way - so many miles of nothingness. You'd see a house and around it twenty miles of desert. What an isolated way to live. Also route 66 I think I'd recommend that over a plane actually.
