Hi'
One more time
Heres an idea , divide the Nats into;"Modern Vintage" Evo, Pre 85 , Pre 90 , and Pre 95, (think ahead), to be run at a different time and place than the "Classic Vintage" ie; Pre 60,65,70,75 and pre 78,(we'll toss a coin to see who gets the sidecars) then we can make the tracks to suit both groups and all the riders', then we will have plenty of time to run the age group races just as Vintage MX has done in the past.
