Moun St. Helen’s did for sure back in the day. Ash made it all the way down to Southern California where I used to live.
I was selling Auto Parts in Texas (Imported Autos only) I had a Customer come in and purchase Every Air Filter I had in stock for His Toyota P/U and did the same for His Family and Friends that He called from the Store. I sold this Guy over $1200.00 in Air Filters that day. We loaded up His truck bed with them. I got calls for weeks from His other Family and Friends ordering more because there were none available up in the NW. Some of these people were changing Air Filters every day just to get to and from work. We tried to Drop Ship to them and were not allowed to because of the Shipping problems. It was stupid but I could have them shipped to the Store and then ship from there to the Customer via UPS. It was interesting Times back then.
