What a treat!
Thank you anonymous whoever you are, what memories this brought back for me... the original Laguna was lethal, unforgiving, the ultimate cajones-in-your-throat jelly-legged blast... what's now the Andretti Hairpin at the bottom of the hill was then the suspension-bottoming entrance to the scariest pucker-up sweeper I ever held my breath through... and the site of a couple of the worst high-speed high-sides ever. Riding that track on the big 2-strokes of the mid-70's was absolute insanity, and these F-1 bikes from '87 in the video weren't much better behaved.
Thanks again anonymous for bringing a smile to this sour old pharts face.
