Keith--- I am so sorry to hear the bad news. I wish you and your relatives the very best and sincerely hope for a speedy, healthful outcome.
In the meantime, I will help do my part to pick-up-the-football and offer assistance in the planning of the event in your absence. Perhaps, as a group effort; we can still pull this off and/or modify the event to everyone's liking.
Again, my deepest sympathy to you and to the members of your family and I will keep you in my thoughts and prayers. Riff Raff
