LOUD Explosion while passing truck! Happened while driving up steep grade on Interstate 70 near the tunnels at about 10,500 ft in elevation. I was traveling from Pennsylvania to Colorado high (elevation not that other stuff.) country.
I was passing a large 'CDOT' flatbed when the explosion happened. At first I thought one of the tires on the truck had a catastrophic failure and I'd be seeing tire tread coming of the truck. Nothing was happening with the truck, he was driving fine.
So I slowed down thinking I had blown a tire out. Car was handling fine. No apparent issues.
I continued to the next exit 1/2 mile or so. Stopped and did a walk around. Nothing apparently damaged with the car. Big mystery. What the heck happened?
I continued to the tunnels and to my destination. Still didn't find any problems.
Three days later I found the damage from the explosion. Suicide bomber bag of corn chips. The sea level packed bag just gave up and ruptured with an explosive sound.
Anyway Skiing has been great. Lungs/Legs still getting used to altitude.
