We wouldn't have to worry about it in 40 years. Farms will be Massive. Talking to a guy in Grand Forks ND said they farm 10000 acres. I said holy chit that's a big farm. He said they are they are the smallest farmers in the area. By the way I was on my way back from Long Prairie Minnesota with a load of cull cows. I still get in trucks from time to time because I love it. Kinda nice 45 years experience and they trust me with the fanciest trucks you can Imagine. I built my farm with a love for farming and a lot of hard work. Trucking provided that off farm income I needed.
