Welcome aboard Newsman.

If they'd only watched the Survivorman Episode where Les Stroud took various parts of his bike and used them for survival. Maybe if they had been out there a few days they might have considered the bikes for what they could use. Then again, they all ditched the bikes to meet up and then tried to walk out.

I'm curious if any of the bikes had an electric starter...

It's amazing that they found one another that night. You can cover a lot of ground on a bike and it's easy to get separated quickly. I'm glad they came out of the situation alright.
