I took a look and didn't see anything about this, please delete/merge if this is a duplicate thread.
Just checked my email and saw this from our coach:
It is with great sadness that we share the news of Ron Johnson. Ron Johnson passed away suddenly on Friday evening. We will share funeral service and other details as we get them. Please keep Ron and his family in your thoughts.
I saw Ron not long ago, swimming at the ASU Mona Plummer pool, just before a noon workout. He looked as good as ever.
I'll certainly never forget my first workout with Sun Devil Masters. Ron was in the pool, doing 1-1 coaching, while the other coach was up on deck giving the workout. He will certainly be missed.
