GenCon 2020 will not be happening. I think this is the right thing to do; it took them some time to get to the point of announcing this, so I can only guess what set of events pushed them over the edge into making this difficult decision.
My son (Thomas) and his lovely wife might be coming to Iowa around that time, since the convention will be out of the question. All of us will be rolling over our tickets for GenCon 2021. Let's hope that year is better than this one.
