Rolling a thought around and looking for alternative ideas/views

[Highlander]

If we have a few people with us, this idea becomes difficult. If it's a large group, the idea dies. So it's very dependant on that.

Why???
If I was in a group and had to bug out, then I would be thinking that I was lucky to be in a group because the more eyes on the ground the better.

The best people cant maintain a look out 24/7 surely the larger the group the better able to take turns with a watch, while still being able to get on with the many other things that are needed to be done
