I've always loved drawing maps for directions. This site obviously appeals to me then. I remember in year 11 I drew a lovely map of Melbourne, complete with street names and landmarks (I don't live there but I know them off by heart) for a couple of friends who were headed over for a concert. One of them asked what would happen if an earthquake ripped through the city, so I drew it in, a great jagged line from the corner of La Trobe and Spencer Streets to the couldn't use it. I think I spent more time in maths class that year doing that sort of thing than what I was actually supposed to be doing.
