IMHO...3 HMRC dates will deter a lot of Houston and surrounding area folks to not go to at least 1-2 of those rounds. At a minimum 9-10 hours and the results of the current poll for premium race tracks, Barber @ 10-12 hours or COTA @ 2-3 hours seems to be a more viable solution. I'm merely speculating on the folks I know around the Houston area and what HMRC rounds they have attended in the past.
