    More good news today. Met with my oncologist and the recommendation moving forward will be aggressive monitoring only. Since I caught it early and surgery was able to remove all of the cancer they aren’t recommending any follow up treatments. Crazy how fast this all happened.

    I’m sure more info will be coming out from MSU, but I just heard that Dr. Vargas passed today. Sad day for the world of turfgrass and plant pathology. #RIPDrVargas

    Not making anyone happy with this. Send him the bill. $350 for irrigation head. $10,000 for labor.

    The decline (and resurgence) of employees in the turfgrass industry. A thread 🧵 1990 ~ 13,378 golf courses (take all of these numbers with a grain of salt. They’re probably not 💯 accurate but the trend still holds up) and we about to boom.

    I don’t have time to deal with people who think today’s actions were justifiable or who deny that Trump didn’t have a direct role in what happened. Feel free to block me if you’re one of those people. Or drop one of these (🙋🏻‍♂️) so I can block you. (For the record I’m Republican)
