Any ideas on how to make money around the country?

Restaurants always need dishwashers and busboys. Here is one Nashville resource.

If you are healthy, you could sell platelets for about $50.

There is also day labor. It pays daily. It is usually hard work. Here is one Nashville resource.

Other options may take a few days to put in place. if that is not a problem, what skills do you have? Office skills? technical skills? Other?

I use an HP Inkjet printer.
Seriously, get some stencils and white and black cans of spray paint. Knock on a few doors and offer to paint the resident’s house number on the curb. You should get a few takers and make some decent gas $$.

You need a white shirt and black trousers,and a black tie, hit a restaurant, you can be a waiter in a busy night, Marina said it best :)
