Anyway, working on a CoC adventure to run when I get out of lockdown. Covid is but a household away. Watching my older granddaughter while her mother's family deals with a case. No worries, few to no correlated co-morbidities, and a better understanding of statistics and the actual infection pattern than the average reporter.
