What is the Supercruise? - Updated early November 2025

Updated early November 2025

One of the original organizers of the Supercruise, at his own expense and time, recorded decibel readings at four locations, but mostly three locations along South Golden Road both for the October cruise, and the much smaller November 1st cruise.

The methodology seemed pretty sound and involved observations for three hours before, during, and in the last hour (8:00 to 9:00 PM) of the cruise, every 10 seconds. Only sound was recorded, not vehicles so direction, numbers of vehicles etc. are not included.

Takeaways - At the observation points on SGR, all the baseline levels were 67 dB for the average. This is pretty loud and comparable to standing next to a clothes dryer. At the observation point on Lookout View, the dB readings were about 50 dB for average. This is normal conversational tone. Over the course of three hours there were, out of almost 1000 data points at each site, about 90 - 100 readings that exceeded the baseline, some by a lot, with the peak being a large twin axle truck at over 80dB. This compares favorablly to the data I collected and reported on below that may be 10% of the vehicles were particularly loud. Since this scale is logarithmic, that 80dB is 1,000 louder than 50 dB. In fact, the 67 baseline is based on my calculation, about 50 times louder than the 50 dB reading on Lookout View. To be clear, whether the cruise is taking place or not, SGR is just loud, probably due to tire noise, engine noise, whistling body panels, and sometimes mufflers and too fast an acceleration. Over the three hours of observation, 18 cars were noted to be probably cruise related and loud by choice. Some of the drivers were warned about their behavior. As I said, most of the data was not about vehicles, but about noise, so these vehicles were particularly egregious and addressed when possible.

Main conclusion - SGR is louder than is desirable next to residences.

End of November Update.

The Golden Super Cruise has been going on for almost 20 years. I recently had a chance to sit down with the original organizer to learn about how it has evolved to what it is, and what it is not. Originally, it was an outgrowth of dragster fans who had street rods built by themselves to share tips and trips and oohs and aahs over peoples’ cars. In the early years it grew to as many as 3,000 cars, but more typico ally 1,200 or so cars of various vintages on the first Saturday of the month would cruise from as far south as King Soopers area, to as far north as HW58. After some community push back, and some self policing of drinking, spinning tires, and trash, the organizers made some participants realize it was not an event for them, and it has now shrunk to a core of more like 3

50 to 500 vehicles. There used to be great expenses for trash pick up and a DJ, but now there is no entertainment, and with substantially less drinking, there is less trash, and people are to police themselves. The stated goal of the experience now, is to “keep it going”, and have fun. As the parking makes use of private property, by permission, and the route makes use of public roads, it really comes down to dare I say, not being jerks. Don’t spin-out, don’t roll coal, don’t rev your engine to increase exhaust or turbo noise, don’t speed, drink, leave trash, etc. In other words, somehow share your love for souped up cars in a very low-key way. Just to be clear, the city does not promote the experience, it requires no permit, we can enforce speed limits, and we can put up more traffic barriers to guide the route differently, but in my estimation, we can not “shut it down” by fiat or declaration.
