It was so much easier back 60 years ago when people could push down a pedal with the left foot, raise the right foot a little bit( or leave it flat on floor board), shift a gear, let up on the left foot, and immediately get ready to do it a couple more times before we got to the next fence row(distance of corn field was usually 1/4 mile)

then they were called race cams-either 3/4 or full race!!!!!!!!!!
