It happens more then anyone would think, A cow moose can get pretty aggressive if she has a calf around and feels threatened, They prefer to walk a nice groomed trail rather then be belly high in powder offtrail.
My brother in law works at a harley dealership that's married to my younger sister, And my other brother in law that's married to my older one and i that hang out and ride with all the time asked Frank if they teach them when they buy a harley to do throttle blips at all the stop signs and red lights..........lol.
Yeah, Cans give you no performance gain, But i guess if it sounds loud you must be going faster..........lol, The moose don't care about the noise, They won't even get off the trail when your coming..............
The younger crowd run cans on there sleds and it can be obnoxious, Its night riding with those cans that get trails closed in neighborhoods that have trails run through them, But you can get fined for excessive noise by the warden if you're not running stock exhaust, Nobody's stopping folks on Harleys that are running straight pipes or rice burners running kerker exhaust.
