Alas, Historicon will not happen in 2020. Fall In in November is possible.

Rob,you beat me to it. This is probably inevitable, predictable,for the best...and a real kick in the teeth. Next year.

A shame but expected.
We will be here to support the event when it can be done.

They are still planning for FallIn in November, but I even think that may be optimistic. Cold Wars is in March. Neither of those are as big as Historicon, but they are still well attended. 

Thanks.
We will see what travel juggling is possible as things open up.
