Despite the temperature hitting the mid 90's in the Valley on Sunday, several hundred people turned out for the annual "History Rocks" event.
It was history, classic cars, music and more at the Myra Museum, sponsored by the Historical Society.
Leah Byzewski, G.F. Historical Society: "Kind of an introduction to the history of the region and the Red River Valley. What brought the settlers here and then we have different buildings that showcase a different time period of life."
Reporter: "And today folks also get an indication of what life was like out on the prairie without air conditioning?"
Byzewski: "Yeah, ha… although in our main building we do have air."
But, beyond the heat were the classic cars, where many gathered to hear the local history that goes with them.
Bob Rynestad, Grand Forks: "Fifty-eight years later I've got the same car as I had at 14-years old."
Reporter: "What's it worth today?"
Rynestad: "Fifteen-thousand-dollars and I paid $325 in 1955."
This 1958 menu that serves as part of Bob's display, is from the Grand Forks, Kegs Drive-In.
Rynestad: "It was lying on the ground when I ate their one day, we didn't have time to bring it back to them, so we threw it in our backseat, 58-years ago… ha."
If you have teen drivers in your home, you might not want to have them hear this part of Bob's history lesson.
Rynestad: "It would go 92-miles-per-hour in 2nd gear, overdrive and we'd slip it down to 3rd and it would get up to 100…ha, ha.."
It's a little history in the heat.
Rynestad: "Like I say, we used to drag race from corner to corner uptown."
