Agree the route, not every turn.
Sit down with a map and agree the general area, the roads to avoid and a time to be home. Kids who help make the plan tend to remember it.
Pick a check-in spot.
Save a friend’s house, the park or the end of the trail as a Place. An arrival alert is a quiet check-in that doesn’t interrupt the fun.
Where the device goes.
A pocket or a zipped bag is better than a handlebar mount, where it can fall off. Helmets and road rules come first.
Honest limits.
Fast movement, tree cover and weak signal can delay updates. Look at how recently the location updated before you draw a conclusion.
