"the word Arizona" or apples & oranges or nuts & bolts
The cable channel Spike TV has on Saturday 12 - 1 pm est first ½ hr Top Dead Center a motor cycle show, then that Car & Driver magazine TV version. I don't know if Arizona has those California sand dunes where folks drive them dune buggies, but on the Discovery channel is a program Tactical to Practical hosted by an x Navy jet fighter pilot that recently told of his top 10 toys for fun, and he included as number 1 as best fun riding high tech dune buggies that look like four legged spiders with powerful engines.
Guess I'am thinking that you might look into speed racing with bikes and cars not on hard surfaces, but dirt.
Or atleast view a desert as a second type racing track.
