I think onroad racing is slowing declining myself. Turn outs at most onroad tracks are less this year then last yet offroad turnouts are huge. Whats going on???
Parking Lot Races that used to draw 150 plus entries now maybe get 60. Onroad Trophy Event turnouts cut in half both at parking lot and track facilities.
Could it be that because all we see in the magazines lately is off road?
I do not think carpet would work in SoCal. Three months out of the year? maybe, but thats it.
Hopefully it will bounce back next year, who knows????
my 2 cents
