I saw this yesterday. This should make things interesting, with other racing organizations/groups running most of the Pro classes that the IHRA used to run. The DRO is resurrecting the AA/FC Challenge, the ADRL is running the Nitro Harleys and the PDRA (and possibly the ADRL) running Pro Stock/Extreme Pro Stock. If the IHRA does indeed return to the Pro classes in 2018 and depending on how things go in 2017, I'd be curious to see which organization(s) the racers embrace. Come on Spring.
