This reminds me of the Race Across America (or something like that) the wife and I rode with (by - they were really going slow) coming back from Laughlin, NV. They were all 1928 or older...we stopped to eat lunch and the support guys were there. In talking with them, the race left from Kitty Hawk, NC and finishes in Santa Monica, CA. The support guys said they pretty much had to rebuild at least 2 of them every night. haha And this guy took 15 years?
