I didn't read it all, but it looks like they'll fly to the loop and back along Lake McDonald. I guess the question is, where have they been flying in the past. (It seems like all along the continental divide.) Also, it sounds like no more flights as of 2030. I hate the noise, particularly after the George Floyd protests in the Twin Cities, so I'm happy to read this.
