I’ve been in long caravans before where anywhere from 5 to 25 vehicles are making the same trek together - as a tree planting and a youth pastor. You know what my rule always was for the drivers? Keep up with the guy ahead of you. That was my rule. It seemed natural because you’re always looking ahead anyhow.
As it turns out, that’s the dumbest thing we could have done. Just one car has to get too far ahead, one car is stuck in traffic and quickly everyone is separated, we miss rendezvous points, cars get lost, pass each other without knowing it, confusion.
Eventually I heard another method for traveling caravans that was exactly the opposite: keep the guy behind you in your rear view mirror at all times. That seemed unnatural, always looking backwards. But it was brilliant!
If everyone followed that rule, then the middle vehicle getting a flat means no one gets lost, because the next vehicle has him in their sights. You can always reach back and slow down, but often you can’t go fast enough to keep up. And you know what? We never lost a vehicle, and we all arrive together.
