Quickmaps is a free website that let's you add comments, notes, and icons to a Google Map. This comes in handy when you use Google maps with directions and want to mark up the map with notes. It can also come in handy in school when having students use maps in their projects.
Check it out HERE.
There is also a help site HERE that gives basic instructions on using the site.
You can create a free account, or just create a quickmap as a guest. As a guest, your map will be deleted when you close your browser. You could print it, or save the graphic file before hand, but I recommend creating an account if you are going to use this more than once.
