If you want to think of ways things can go wrong, have at it.  Personally, I am thrilled with the new information and will plan two trips this year.  How much can go wrong when all you do is cross the border at International Falls and drive to the Beaverhouse parking lot?  I am much more concerned about the fire danger closing the park than I am relative to issues involving Covid-19.  Actually, I am more concerned about bugs than I am about the Canadian government handling of the border crossing.  Furthermore, I think the fishing is going to be great this year because the fish have had over a year to recover from being attacked by all kinds of artificial lures
