Losing our geese is always a bad thing, and it has happened on every trip to some degree. Here is a proposed geese herding aid that will allow you to know where your geese are (if you are inside tower service that is).
It is a phone app called Life360
https://www.life360.com/ the premise is that one person downloads it, cranks up a group and invites the other riders to join in the group. Once a group code is assigned, all the players download the app and plug in the code to join -- wammo, they all show up in the app map located spatially relative to each other.
Everybody gets the location display that includes the whole group. Everybody can see, including the lost goose. This would be the cat's meow if somebody had a breakdown or, heaven forbid, somebody actually went off into the bushes in a non-obvious fashion. Or parked on the wrong side of the knife store and
got everything turned around accordingly.
It can do group messaging and similar teenager techi stuff, but the fact is that it will always have a named dot for each of your ride participants and as ride leader you can herd your group of errant geese a lot easier by using it when you come up short a head -- you can see where they are easy peasy.
Then when the trip is done, everybody deletes the app. Neat and clean, that.
Funny thing, we lose more people at pit stops and in the towns than we do out in the boonies. More traffic lights and turns available, I guess.
