Signs

Hitchhikers often debate about weather to use a sign or not. If you decided to use one there are several important things:

• Think well about what place or text to put on it: take well known places, sometimes also road names can be used or more humoristic phrases ("I don't stink").
• Use the same font as the route directions
• Use contrasting colors: black on brown cardboard is not very good readable for passing drivers, black on white is far more readable

Tip: Make a sign of a large sheet of brightly colored paper glued to a sheet of cardboard. Cover this with self adhesive transparent book wrap. Now you made yourself a re-usable sign wich you can use with a whiteboard marker and clean again with a small towel.
