I don't have any first hand experience with leading Cruise Moab Runs, but I've lead several 40's Only Runs with fairly large groups of 15-20 rigs and one thing that happens often is running into another large group coming the other direction on the trail and trying to handle getting 30 rigs around each other without tempers flaring. I think in situations like that, diplomacy and courteousness is key. Stop, get out of the rig walk up to the other group and try to decide the best way to proceed while being as friendly as possible, even when it's 20 side-by-side atv's full of tourists from texas. I've had a few occasions where people want to yell and cuss and be difficult, and it's hard to keep the blood pressure down. But, it always pays to be the one who keeps their cool.
