my old track in SoDak (Thunder Valley) held I think 2 or three 10.5 races this year. Good crowds showed up and most of the complaining was about limited runs due to the "bracket cars" that were also running that day as they shared an event day. I'm betting the street tire race will be held independently next year. Steve Sherman started a "heads up" series and holds a few races a year at Barona down by San Diego. I'll be racing in my second one turkey day weekend. He knows what the cars run, and makes pairings. It's fun, the people are great so it makes the long trek very enjoyable. Side bets are welcome and encouraged, matter of fact, two big dogs have agreed to leave $2K at the line, and only one will walk away with $4K. Check it out on Facebook at "Match Race Madness". I could see this working at about any track.
