That is cool they are guides, an awesome career and service to the people.
Transporting 900lb of weed (valued at $4.5 million) is not an odd job to pick up some lift ticket cash.
No offense, but your friends are ####### morons.
If you are committing a felony with decades of potential prison time that involves driving 1000+ miles across state lines and you don't have the common sense to spend $300 to fix your windshield then you probably deserve whatever is coming your way.
That being said, I hope they get off on a technicality.
