Thanks

Where did you find the 24 hours?  I've called several offices - Washington, Chicago, International Falls, and Ely - and not one person in that part of government would commit to anything other than what the law says - immediately.  I got some to sort of suggest they might ordinarily overlook any time between when you entered the US and when you "left the wilderness" is long as you reported soon after that.  I figured if I took several days to paddle to an EP after a trip through the Q, it was fine.

You can get an I68 as well and never have to report.  Figured if I ever did my fantasy Lake of the Woods to Grand Portage trip I'd do that and a sat phone and be 100% legal.  (I hope that isn't politically incorrect to say - since it suggest there are people that cross the border illegally.)

And the Rangers don't care about RABCs.  I've never needed mine, but always had them.  And based on posts on another board, I'd estimate half the people never check in with the US Customs.

I'm taking a Wilderness First Aid class in a few weeks and the teacher is a US Border Patrol agent and Scouter and I plan to try to get him to help get me a more definitive answer on reporting.  We'll see.
