my grandpa used to have a giant tank of roundup on his 3 wheeler and one in a pickup and on days when there "wasn't as much to do" he drove around and round upp'd all his fence lines to keep cedar out!
But they made good fence posts when there were no trees anywhere
I ask this with all due respect and seriousness…did he die of cancer? Lot of those guys who were exposed to Roundup 24/7/365 have.
Amazingly no cancer. Grandpa was pretty amazingly forward thinking though and a rule follower, he never used leaky/broken equipment, got conservation plaque's for soil and water stuff that he did to improve erosion etc.
And he farmed/ranched under 1000 acres. So everything he was doing was scaled down quite a bit from what guys out West do.
