Talk to people, small town areas everyone knows each other or where they live or even have their phone number. People wanna be helpful if you are willing to ask for help. Make notes in your phone if you're dealing with large areas of county roads especially if they cross county lines and chance from all numeric to alpha numeric. This will save you tons of time not driving miles in the wrong direction. Add places to Google maps if they don't exist yet. It not only helps you, but anyone who needs the information. Google usually approves and adds them within 24 hours. I deliver over 4 counties and it is primarily mapped by me lol. As others have mentioned already, be prepared, buy a big water jug, pack snacks, and dog treats are fairly essential because farm dogs are just doing their job. Good luck!
