Unless I wild/stealth camp, provincial parks charge ~$35/day which makes it impossible to keep below the $15/day ($15/day is just a number I've heard mentioned elsewhere). I could try borrowing someone's CNIB (Canadian National Institute for the Blind) card for cheaper camping prices but likely, when they see the bike, they won't fall for it.

Do others bike tour for ~$15/day? How do you achieve it or is this just for food?
