Quite a while back, early in the Covid lockdown, I hypothesized that certain vehicles had not been moved for a very long time, based on the sediment deposits beneath them and other clues. [Those were the early days of working-from-home and grocery deliveries and other activities that allowed people to stay home and still survive.]
This car, however, seems like it has been not-moved for far longer than just since Covid. What a fine microenvironment for mildew and mold! (Ick.)
