I have a friend who used to be homeless in Toronto. He has mental health issues, addictions, etc. He has caches hidden around the city, that hold extra cloths, extra winter coat, a pair of winter boots, sleeping bag, tarp, some food and water. I'm not sure what else he caches, or how exactly he does it, but he recently moved out of Toronto, to a city a few hours West, and he was planning to set up a cache there as well.

A few weeks ago, he was visiting Toronto for medical appointments, and had a huge miscommunication with the person who was supposed to drive him back to his new home. He ended up spending an unplanned, but comfortable night in one of the city parks. He said all his stuff was still exactly where he hid it.
