I just discovered this new thing today called Google My Maps. It is on your Google Drive, just hit New, then More, then My Maps. It's really cool if you're making a course map. You can go anywhere on Google Maps and make lines and things on the map. You can even measure distances! Man, I wish I had known about this before. I've spent long hours trying to make course maps using Paint and Google Drawings, when this great tool was right under my nose! Highly recommended to anyone creating or revising a course map.
