Start by the world trade center and run south north on Naito Parkway for 1.65 miles, then turn around. On your way collect each of the following items I saw on my run today:
One flattened and dried rat carcass
1/2 of a dead crow (the rest has been taken)
a used syringe
the non existent toilet paper from the only port o potty along the way (the one with graffiti on it in the grass, a little before the turn around point)
cell phone video footage of the train that prevents you from moving on for 10 minutes.
the odor of something fried in old oil at the Saturday Market.
First one to do this, wins. You can keep all the prizes you've collected on the way.
