Rideshare driver and grocery deliverer
Rural areas might be smaller, but they still need ridesharing and delivery services like anywhere else. In fact, at times, the need is even greater than in the cities, especially since so many rural areas have limited public transportation and residents without cars might need a little bit of help to get their essential goods and services.
It could be anything, from a drive to the nearby town to get specific groceries to a ride to the closest airport. You can sign up and work for companies such as Lyft, as they always have side jobs for seniors. You can also try signing up with services such as Instacart and Shipt and delivering groceries to your neighbors.
