A friend recently did a book drive for an assisted living facility. The residents are the most vulnerable and aren't allowed visitors, so she had people "sponsor" a resident and send them books -- activity books and puzzles and such. I'm sure other groups could benefit from such a drive as well. Would that be helpful?
Parents with kids at home also might like to have activities. I'm not sure how to do it in a safe way, but a live reading (online) for kids in the afternoons? Book club for bigger kids?
