30 years ago my dad was just like SD, I'm a big city boy now! Sell the land yada yada yada. I didnt go to college and study computers to be a cow/wheat/corn/sorghum farmer etc etc etc.
Then he retired, inherited a little bit of land and now he is all about that farmer life because he has nothing else to do.
Just saying SD, maybe hold on to a lil bit of the land so you have something to do in your 60's.
