I'll link Tim's stories back to his original Racing History Minute post about 1962 Daytona from a couple of years ago:
Great story Tim, I remember the old draw bridge that crossed the river in Jacksonville. While not terrified of heights I do hang on when off the ground more than 10 feet. Every time we crossed that bridge in Jacksonville I would get that funny feeling in the pit of my stomach but still could not stop myself from looking through the metal grating down to the water way below as the tires made that weird sound while on the grating.
