Flickr is an incredible thing and I love to wander through the EDM Flickrgroup and look at all the work members have posted (almost 13,000 different drawings and paintings!!).
I just discovered a cool feature called 'geotagging'

that lets you zoom into a map and identify the exact street corner where you did a drawing and mark it, It's interesting to see all of the little spots I have pollinated with drawings. If you are a Flickr-person, consider adding this information. How cool it would be to be able to compare drawings different people had done in the same location!
