I could be mistaken but I believe they move materials in rock quarries, at least that’s what I saw on an episode of some discovery show many years ago. I still think about them regularly too since it’s like 3 stories tall and has a stair case to get to the driver seat lol
Older brother, we live halfway across the country from one another. We play video games almost nightly in Discord as a way to keep in touch. Visits are a couple times a year it wasn’t always good but the 5 year age gap gets easier to overcome the older we get. Both in our 30s and we align on most things these days.
I could see that, I just worry that leads to complacency rather than a broader interest. Of course we don’t have much history for this to grow from yet!
