I don't know anyone on here from Calgary,but there may be.A couple of years ago a few guys from Toronto went out to help in Calgary for a few weeks.They said they are so short on drivers that bringing back missed is a daily occurrence because everyone goes out over dispatched.I guess that's ok if you like OT which I don't.Why not just pull over and chat with one or two of them while they are delivering.I'm sure you'll get better answers from them than on here.
