Who cares if it gets busier, we should hope it gets much busier! It's literally one of the most beautiful places on earth, certainly one of the most accessible in regards to flight access, with a perfect 4 season climate. This has huge "Jackson, Wy" potential, with hopefully, 4-5 areas you can now stay and enjoy, with a world class city/downtown 50min away. Shit, build another golf course or two for all i care. You could double or triple the size of the fortess and nakiska plans, allow banff to grow by another 25%...the impact on the environment would be completely negligible
