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.

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.

It is with great sadness to report the loss of one of our turf faculty. Dr. Uddin was much greater than just a turf professor at Penn State. Do a search on twitter for “Wakar Uddin” and see all he did outside of the university. #RIPWakar

Saddened to hear of the passing of Rohingya activist and my friend Dr. Wakar Uddin. My recent visit with Rohingya refugees in Cox’s Bazar made clear the continuing importance of his work. Dr. Uddin was a powerful force for the Rohingya community and will be missed.
