this is happening, im organizing it. you wont know the checkpoints until the day of the race. the race will be invite only, to prevent hazardous situations (aka little kids getting nailed by taxis.)
ill provide a checkpoint list with a list of tasks needed at each checkpoint, and maps of the city for everyone with the checkpoints circled.
everyone who is invited to race MUST have a camera, if you dont, you'll need a partner with one. it doesnt matter what kind, point n shoot, SLR, video etc. as long as you can capture yourselves at each checkpoint, its fine.
