I drove to the Weiser (Idaho) fiddler festival on the weekend following the eruption of Mt St Helens. Met some folks driving in the opposite direction who’d changed air and fuel filters multiple times... one particular dead head told me when I asked if he’d seen the ash... “Yah, been through all them changes man.”
I only had to replace the Honda air filter once, and we were a week out and 500 miles away...
~LOL~ we were in Tahiti when it erupted.
