Drag racing is like any sport. There ae purists who know whats going on, there are casual observers and there are new fans. As a purist, I will travel 3000 miles to watch a race (I have, more than once) and I've been a diehard fan for over 30 years as well as doing some bracket racing when time and money has allowed. When I went to the Motorplex this year, I was only able to attend Saturday and Sunday but I was there from gates open to concession closing time taking in the sights, sounds and all of it. Long days. However, casual fans may or may not care about the history, the mechanics, the "show" and who the racers are outside of a few big names. New folks definitely don't care for probably the first five races. They are usually just thrilled with the burnouts, the noise and greasy track food. So I can appreciate if a racing season as a fan included a couple NHRA National Events, but if I can introduce someone new and spend 6 hours watching 1/8 mile nitro and seeing some close racing, 250 mph+ speeds and share that experience, I'm all for it. Not to mention at half the price.
As someone originally from Canada, I equate to hockey. I can go see the NHL for $150, I can go see a minor league game for $50. If someone has never the seen the sport, the $50 ticket has much more value. And as a fan who enjoys hockey and only has $1000 to spend on tickets the whole season, I'd rather watch 2-3 NHL games and fill it in with a few minor league games because even though the skill and polish is different, the competition and excitement isn't.
