Was thinking about the Old Daze, when we had NHRA, AHRA, IHRA. Biggest difference I remember was that AHRA had 16 car Pro fields, but booked in 8 cars to run the whole series. Like Don Garlits, Chris Karamesines, Don Prudhomme, etc. NHRA started first, around 1951 more or less. Then Jim Tice in AHRA late 1950s, and Larry Carrier in IHRA around 1970. AHRA died in early 1980s. I was fortunate to see last AHRA Winternats at the old Tucson Dragway. Larry Carrier at IHRA was one of a kind, but he gave NHRA a run for the money. I am surprised that IHRA is making a comeback, but I hope that it will balance things out. Back in the Daze, the 3 HRAs did give drag racing a balance, and racers could choose where they wanted to race. Hope the new IHRA brings that back.
