Part of me hopes they are on foot because I cannot imagine that 2 young men from Port Albernie could ever be prepared for the remote bush of N Manitoba or N Ontario, the bugs, the terrain, the wild animals, I doubt they would last long out there on foot and it sounds like they no longer have camping gear, seems it was burnt with the Rav 4. Unfortunately if they were to die out there in the vast remoteness their bodies may never be found.
JMO I feel they are likely in another vehicle and they likely drove out of Giliam before the Rav 4 fire was discovered. Where ever they are, it has me on the edge of my keyboard. Hope they are caught soon.
