In order for USAC or any National series to thrive there must be genuine interest created on a National level. WoO packs them in because 410 winged sprints are a staple of short track racing nationally. Same for WoO Late Models. Traditional sprint car racing has only pockets of interest nationally and that needs to change. Traditional sprints are currently popular in the midwest (IN, IL, OH, & MI), Southwest (CA, AZ, NM), with marginal interest in the Plains states (KS, NE, OK). Regional series, whether under the USAC banner or not, will serve to provide a driver pool from which the National series can draw. That will create interest among the fans in those areas to follow their guy. When the USAC National series comes to town you will then see WoO size crowds. That, in turn, could prompt other areas to try traditional type open wheel racing and on it goes. But this is a process that takes some time. Simply finding money to pay larger purses is merely a band aid. The long term fix is in creating national interest through regional series or individual tracks that will provide drivers to the big show and fans to watch them.
