hi rob, i went to three world long track finals in the 1980's - korskro, marianske lazne and herxheim. all three of these circuits were shale based and resembled very large speedway tracks. i recenty read an article by ivan mauger, where he comments that all pre 1991 long track competitions were more like speedway compared to the current long track series which resembles grass track with very few speedway riders taking part. it's just another example of how the sport has evolved over the years.
