50th Sturgis Rally 1990. It was a very hot week with temperatures in the 90s. Some people say that the pavement was melting but I would say that the thick black ooze was an accumulation of dropped oil from the thousands of Shovelheads that were there. Remember the Evo hadn’t been out all that long then,about 6 years so they were probably in the minority amongst the 600,000 Harleys that went to Sturgis in 1990. I remember that flyers dropped onto the tarmac sunk into the surface and disappeared under the gunk.
My denim jeans had black stuff ingrained into the knees where I had knelt down to take low shots.It never came out, I shoulda kept those jeans with a bit of the 50th in ‘em.
