There was also the socio-psychic factor. Every now and then when life gets complicated and the weasels start closing in, the only real cure is to load up on heinous chemicals and then drive like a bastard from Hollywood to Las Vegas. To relax as it were, in the womb of the desert sun. Just roll the roof back and screw it on, grease the face with white tanning butter, and move out with the music at top volume, and at least a pint of ether.
