You could try asking people at area truck stops. No chance of a ticket/arrest, get hit by someone or something and most people usually pretty friendly. Besides most major truck stops have showers so you can clean up, they have coin op laundry, you can grab a decent meal and may catch a ride with someone. It helps if you don't smell like dirty socks that haven't been washed in 6 months and smile even if they say they can't help you. Thank them any ways.
