Marcon 55 was a convention held in person September 3-5, 2021 at the Crowne Plaza Columbus North in Worthington, Ohio, near Columbus, OH. It had been scheduled for May 8-10, 2020 at the same location, but it was cancelled in mid-March 2020. It was rescheduled as Marcon 55 2.0 for March 7-9, 2021; this does not appear to have taken place, though it may have been held online.
