Remember, you asked for specifics
...here comes my verbal diarrhea, cover yourself!

I've only heard referance to the CNN piece, haven't wittnessed it.  And only side I've heard from is the Angle "locals".  Here is the "second hand" story as I heard it.  Cooper says he's coming up to do a story on the Angle and border "issues".  Wants some interviews.  Locals (granted, only 4 that I talked to) state he does a spin job and the real story is lack of security on our National borders.  The bar owner, resort operator, Bombadier driver and local tavern customer tell me he showed the Angle as another example of a gaping hole in our nations security.  Presented it as prime pickings for terrorist insurgency.  Showed it as an example that needs to be shut down.  (Again, I didn't see the piece).  These folks felt slighted, as the story pushed for tighter border crossing security.  They are totally dependant on Canadian customs for anyone who desires to driveup there.  They all told me the newer, tighter regs are putting a crimp on those who are not familiar with border crossing and scares away traffic.  They say Cooper didn't even go out on the lake or into the area.  Showed up for a little while, does his interviews and leaves.  They felt that shows he had a pre-arranged agenda for the piece.  (Personaly, I don't care).

Now hold on as this gets complicated....

This year, new regs were put in place that is making it harder on the US locals to enter into Canada and back out, once inside the Angle.  You used to be able to use a 24 hr phone on Cyclone isl....just accross from Flag Isl (unmanned, but open to use in the winter).  You'd lift up the reciever and tell some customs agent off in Quebec why you wanted entry into Canadian side of LOW/Ontario.  They would or wouldn't grant you access right there on phone (or supposedly they could also ask you nicely to please return to the American side of the border...HA!).  Very convienient for the US resort owners/and their customers on Flag and Oak islands.

Now any patron who wants to come up and sled some, has to drive ice or sled back to Young's bay (mainland Angle), then drive back to 4-corners (near inlet village) to the video phone and hit the "Canada button" and request entrance.  You then go drive/sled, back the 15 mi to Oak isl and do your Canadian snowmobile trip.  (So a 30 mi round trip to get clearance to enter Canada to the North and a 30 mi round trip to clear US customs upon your return).  Upon re-entry from Canada, you used to be able to "check back in to US" later on, when you left your stay, and "hit the US button" back at 4-corners, and tell them you got back from Canada yesterday.  You then would then immediatly hit the "Canada button" to request entry back into Canada as you're driving back home out of the Angle (again into Manitoba).....en route back to the contiguous 48.  Oh yeah, you gotta hit US customs again as you cross back into the US out of Manitoba.

You can see how complicated this becomes, they feel they are being economically deprived by the current "farce" of things.  I agree somewhat.  All this checking in and out on this island or that island....is useless (IMO).  It's all via remote and there is no one there to....
1) stop you
2) see if your story is real
3) see that you really use the system and don't just cross willy-nilly as you please.
.....I was told that resort patrons have already been fined by the US for checking back in from their Candian afternoon snowmobile trip....because they got back to 4-corners in too much of a delayed fashion (you can imagine what that does for repeat buisness).

It's a total honor system up there.  Two years ago I get to the video phone as we crossed back into MN at the Angle from Manitoba.  The phone has a sign that says...."video camera not working".  The US agent asks me on the phone to describe myself.....then asks, "is anyone with you" and "who".  "Put them on the phone".  He even asked me to "read your description on your liscense to me" (I hope he was checking it against reality in his computer).  Again IMO, it's all a farce and does nothing to increase security and slows down and impedes economic use of the area.  It serves only to give the "illusion" of increased security.  If they told me I would be denied entry....who's gonna stop me?  Who can even legitamatly verify my identity via remote?

Sorry so winded...
Yeah, it's open border, but I think it's the least of our border security holes at the time.

(does a RABC permit cover this part of the border.  Would that be easier?)
