The amount of trash people leave at Princess Louise Falls is downright disappointing. Now, if the City were to spend the funds to put a rubbish bin near the Falls, then it would probably result in an even bigger mess, as people would take those trash cans as license to leave even more crap behind.
There seems to be a breakdown in the cycle here. People are generating too much trash and the city isn't picking it up often enough. If the city were to increase their collection cadence, people would generate even more rubbish. Two lessons here: 1) Nature abhors a vacuum, and 2) You can't win.
