Thanks guys,
I knew about the restrictions on driving to camping events, and on driving other Scouts. I am a retired cop, and would never allow this in any case. I was just caught by surprise when my 17yoa son came home last night and told me the Scoutmaster told him he wasn't allowed to drive himself. This was not an issue with my older son, who is now 19yoa and serving as an Assistant Scoutmaster, as am I.
The Scoutmaster hasn't changed, so I thought maybe the rules did.
I'll discuss this with the Scoutmaster.
Thanks Again
