Well the Hoover Dam was on a massive scale and had some nice 1930's architectural embellishments. We took a detour to see it and I think it was worth it. We continued on south along Route 93 until we met Route 66 at Kingman. The Americans' have commercialised Route 66 a little more than I had hoped. A lot of the signs were fancier than they should have been - bright pink backgrounds and brightly coloured text telling you that you are driving along the historic Route 66. Maybe this is something we should do for the M25. The drive itself is nice enough and after doing this section I wouldn't mind doing more at some point. A railway runs parallel for quite a bit of it and we saw numerous freight trains which were far longer than our U.K. freight trains. The towns along the route are all a little run down with old petrol stations and abandoned cafes. I am guessing this is due to modern cars not needing to stop so regularly compared to the cars which would have driven along...
