Almost 30 Years Ago...

Due to a series of unforeseen and insignificant events (too insignificant to mention here), I came upon a published class breakdown for the HDRA (Harley Drag Racing Association) circa 1985.  This was from back in the good old days when Red Roberts owned and operated the HDRA.  Though titled 1986 Classes, I think these are the same classifications that were used in 1985 (at least they are in regards to the class I was involved in back then).  As far as I know the 1986 HDRA national tour did not take place due to circumstances beyond Red's control. Unfortunately I don't know the name of the publication this came from, so I cannot give proper credit.  I offer it only in the interest of presenting a little drag racing history to those of the younger generation who care about such things, and to jog a few good memories for those of my generation.
