You can make your original map,,,
to tell your friends of the next BBQ location,
to tell your colleagues the restaurant for welcome party,
to tell people of your shop in free market
to tell your fan of your next street live, etc.
Today, sending an URL of map via mail is very easy.
But, drawing your original map may be fun and you can make it
more impressive and more understandable.
Place some streets, railways and rivers on the canvas.
Then place some landmarks on the map.
From the stamp catalog, you may choose road signs, map symbols and variety of icons.

You may put your own photos or graphic images.
When you draw a route guide, taking some pictures of the landmarks on the way is a good idea.
Your created maps can be exported as graphic files to share with your friends via email, message, iCloud, Dropbox and etc.
