When living in Kentucky, I was once once having a discussion about travel, with the lab technicians that worked for me. I explained that next time I traveled to my home state of Utah, I was considering taking the I-40 route, as I had never went that way. I explained that I hadn't been in New Mexico since I was a young boy, and stood on Four Corners.
One of my lab tech's said that he didn't know how I would go through New Mexico on I-40, as New Mexico was in the country of Mexico. I stated that no, it borders Mexico, but it is a state in the United States. The other two lab tech's joined in and also explained that I was wrong, and the first lab tech was correct about New Mexico being in Mexico.
At first I thought that they were just having some fun with me. But I soon realized that they were dead serious. I had to pull it up on Google Maps and show them.
The kerf of the blade didn't matter to him. He was looking for "rough cut" boards.
