Marissa - You can also so volunteer work from home. Animal shelters need people to make phone calls and assist with placing animals in foster homes and such.

A couple of years ago I helped a woman who had volunteered her services as an interior designer to redo our local pound. She needed some one to make calls to help coordinate volunteers for things such as painting, calling contractor's, making calls for donations, etc. It was great and the pound looks so pretty.

So there are many volunteer opportunities out there that you can do from home if transportation becomes an issue.

I am not sure of the size of your town but there are organizations that help with transportation for the disabled. They come pick you up, take you to where you need to go, and bring you back home. The cost is usually free.
