Sorry Verne, I look at your scenario as a good thing - at least these kids are not racing out on the street in their 5.0's, weedwackers, etc... I've been through the same frustration you have, and can relate more of the same types of stories. However, a test-n-tune is indeed a Friday night 'open' event for people who want to run their drivers - not a serious race car tuning session. When I want a serious session, I get together with a bunch of buddies and we rent the track for the day!
I think Maple Grove Raceway has done a phenomenal job at resurrecting that track, the events, the concessions, the restrooms, etc.... It's a nice place to go with your 5 year old to see some tiresmoke and wheelstands. The best event of the season is the Dutch Classic, come join us!!
BTW, I've learned that to get the most runs in on a t-n-t night, one should be in line when the gates open, be the first person in the tech lane, and stay until the end. I got 4 runs in one night night even though some 'racer' oiled the track down 2x, another 'racer' went into the sandbox, they eventually shut one lane down..... cool night air at 10pm, can't beat it
