Of everything in the Rockies, only grizzly bears scare me more than moose. It's extremely large, powerful, unpredictable, aggressive, and can run or swim faster than any human. I've accidentally crested a hill and been almost as close as they are, and that was existentially terrifying.
Ah yes, this reminds me of the yearly dumb Americrackers who get drunk and hospitalised in Canada for literally exactly this.
