It was late on a Summer night in 1974. I was out testing my recent tune-up on my 67 GT 500 (427 Medium Riser, Tunnel Wedge, Dual 660's) across a bridge on a county freeway. I proceeded to a turn around spot, crossed over the median, checked for traffic ..and hit the throttle. Accelerated to about 100 mph, then backed off and coasted around a corner, heading back to town. I happened to glance in my rear view mirror. and saw a set of blue lights behind me about 3/4 of a mile back. Being young & immortal ( or so I thought at the time ) I decided to try to beat him back to town and lose him.Well. I had installed on my car awhile back 2 modifications....A) a cut out switch to the tail light system & B) a flip down license plate with a choke cable running right next to my driver's seat. Pushed the cable, hit the switch, and went for it. I pegged the speedometer,crossed the bridge, headed up a hill and turned right into the city streets. I had a friend whose parents lived nearby, so I drove down their street, shut the car off, and coasted behind a large hedge next to their driveway. It was an unlit street. and having a Nightmist Blue Shelby, hoped it would conceal me. I rolled the window down and listened. Heard a lot of radio crackle for awhile, then everything was quiet. To be sure , I slept in the car till sunrise, then went home.
