 As the 1930s began and speed records were being broken regularly, the Bonneville Salt Flats was found to be preferable to the sands of Daytona Beach or the Monthlhéry track in France.By 1935, the course was attracting international attention and in July of that year, Jenkins provided accommodations to British driver John Cobb and even relinquished his spot on the flats to him.Cobb succeeded in breaking Jenkins's records during the run.
