I'm sure others know more about organizing these things than I do but I was seriously thinking of competing in the series when I looked last year and realized most races were within a 2 hour drive of home. This year's races include one within a two hour drive of my home. If you're trying to get more turnout per event, the way to do that is not to shift the location of your typical race to be farther away from the state's population center.
Given the locations, if I do any event this year, my list of options is down to 1. If the schedule were similar to last year's, I very likely would have done 5-6 events.
