"When was the last time you had to spend 15 minutes planning out where and when you would meet when because your group is splitting up when on a trip?"
I do these things all the time as many of my hobbies are outdoor activities. For example, at Arapahoe Basin, a ski area in Colorado near Denver, cell reception is non-existent. So you need to have a plan for people to meet up when we get on the mountain, where to meet for lunch, where at the end of the day. And even at ski resorts with cell coverage, it is far easier in a group to discuss how you are going to meet after the run because people will invariably get separated. E.g., if I'm at Vail, "Meet on the skier's left side of Northwoods, do not go all the way to the base."
I always bring paper maps when backpacking and hiking. Sometimes when you are going camping, you have to have this all planned ahead of time since once again cell coverage may be non-existent. And someone always knows where I am going and when I should be back in case I need a rescue. I also go caving as a hobby, and all of these things are especially important there.
