And I'm telling you this is rural Ma, the people out are townies. There is no lockdown here- there is a "stay at home" order and people are allowed to go out for a walk.
You are free to come to Ma and go to every single rural town and stress that people need to avoid social contact. I'm sure this is the case for most of rural America.
I'm done here.
For a third time; the issue isn't with individuals wanting to go out for a local walk it's with the groups as you described. If it's people from urban environments travelling to rural and/or isolated communities / spots near to them then that would also be an issue.
It shouldn't be surprising that people are pointing out that among millions locked down across entire countries that yes, there are parents that are managing to get their children to respect lockdown. In the UK your son would have to explain to the police for himself why he was outside with his group of friends. It might not be that severe in terms of mandated requirements where you are but treating it seriously before it gets to the point where you
need to is a point in trying to prevent it from getting that far. Again, going out for a walk in your local area isn't the issue it's the mingling and grouping you describe that's been seen as the problem.
No one is saying it's easy, but we're also not talking about your average Thursday where your child (or anyone else's, for there's a reason his friends are out) wants to see his friends.
