Claire,
I was sad to hear the news of Tom's passing. I've played disc golf with him a few times, and talked to him many more. He was a great person, and a great mentor to his group of disc golfers. Tom was always giving away discs to new players that needed them. We'll miss him.
I have not heard about a memorial tournament for Tom, but it sounds like a great idea. If you do find out about it, let me know. I'll be happy to promote it at the shop. - Thanks, Patrick.
