I'm sad now at the state of the world, that would push me over the edge. Planning a big trip to Europe in July 2022, I reckon I'd have a 75% chance of this happening by then, and yes, subject to a vaccine.
Goodwood early July (best guess), possibly Cardiff SGPa week later? If I stay as long as 4 weeks, maybe Wroclaw SGP if end of July?
Agreed 2021 a washout, at least for Australia.
