Rural. That probably makes it harder, admittedly.
Yes.
Back when I was living in metropolitan areas, there were dozens of options available. Now that I live in a rural area, it’s far less organized/centralized.
If you have a food pantry within an acceptable distance, you might look at volunteering there on a periodic basis. When I’ve worked at food pantries, our big job was mostly weeding out expired food.
In my rural area, we have Meals on Wheels. When we used to do meal deliveries, it was on a schedule, and during the workday— but you might check with them to see if they have additional options available that don’t involve actual delivering, and can be done irregularly.
If you check whatever your local senior activity center has, there’s often a local place that provides free or low-cost meals for people on a fixed income. You can see what you can contribute there.
Some of the local churches might have a clothes closet where people can bring donations, and it gets sorted and organized and sold at garage-sale prices. So if you don’t have a place nearby under the Goodwill or Salvation Army umbrellas, you might check who’s organizing that kind of thing locally, and if you can help sort or tag things periodically.
There’s also often an informal group of people who watch out for those who are ill or recovering from surgery. They coordinate amongst themselves to make sure that dinner is provided, so that there’s always someone stopping by daily to check on them, visit for a few minutes, and so on. So you need to figure out where that group of people is in your area, or who would know how to find them so you could pitch in when you’re able.
Good luck!
