So far it seems just to show that the best way to get around in Canada is by car and if you ask nicely someone will take you for free!
Yes, they're obviously hitting some fairly remote places. They might get lucky with buses in some areas and train coverage is very limited (and expensive) so I do see them doing a lot of hitch-hiking. That budget really isn't going to get them far. Not much is cheap in Canada, especially food and drink. I'm sure they'll discover Tim Horton's though!
It was hard to make too much judgement of them on the first episode. The brother who lives with his parents could really struggle. I can see the father/daughter having a falling out too.
