Given the unprecedented times of COVID-19: Party? Next year (hopefully). Ceremony? Minimal people.
A big in person party would've been morally indefensible even if not actually mandated against. So the obvious solution given Nick's long history with teleconferencing was a Zoom wedding. So ceremony by Zoom, and not really any after party. We'll have a party with dancing and music and bonfire in the future when the world is somewhat less infectious.
Ceremony: Saturday April 25th 11AM Pacific Time 2020.
