Check out Immokalee Drag Strip that's been running on an airport runway for the last 20 years.

There's always a reason something won't work. But if Wally Parks had listened to the folks in Southern California who bad mouthed all those black jacketed and greasy drag racers in 1950, there would be no NHRA. And there would have been many more street racing deaths than there have been.
My suggestion wasn't for assisting temporary tracks to race Pro Stocks, Top Fuel or even 8 second bracket cars. Most of these events are for ways to get kids off the streets in their street legal cars.
Yes, the new cars like the Tesla Plaid are making this harder, but it's the high school aged kids in 13 seconds and slower cars that cause most of the street racing damage. I remember it all too well... Back in the 60's, I was one of those kids. My last street race was in 1965 against my best friend and he almost took out the side of County Speed Shop in St. L. when a little old lady in a Rambler pulled out of a side street just when we were both banging 3rd gear. Even after that, it was only because we had Alton Dragway and MAR close to us did we stop street racing.
The people who are trying to help stop street racing by putting on these events are not the bad guys. They are trying to stop typical kids from racing where your family is driving. Without someone's help, they will continue to do things wrong and hurt people. Or they will be forced to give up and street racing will continue in your neighborhood.
NHRA can hide from the problem and just make sure their not liable for any harm, but the image of drag racing will never improve or become main stream.
Wally Parks original idea was to send the NHRA Safety Safari on the road to preach the gospel of quarter-mile speed and
safety. (It was a good one at the time, but with today's automotive technology, maybe 1/8th mile racing would be a lot smarter.)
