    Your First 50 mph/or Faster Patch

    My first run at a time trial was around 1977. Ran a Hughey round nose with a K&B 40. Got 37 1/2 MPH! First SAW record I got was at Huntsville Internats. Forgot the year but it was the first year using laser sights. All the previous records were "archived". Ran 79 and some change. Before...
