When Brock Yates set out in his Moon Trash van in 1971 to see what was possible on a non-stop NY to LA run, he started a movement. This year, there have been at least 21 drives and 11 new claimed cross country records. Ed Bolian discusses that here.
In the 44 years since that drive that started it all, 8 cars have held the elusive NY to LA. Here is a link to some photos all of them.
