RE: atv noise well hunting
the farms i hunt i also ride 4 wheelers on for play and we meaning 4 atv riding together have come up on a doe and two fawns before withing 15 yards and they stayed still i always figured the constant sound of the engine and sounds of the ag equipment they are used to it and dont feel in danger but know riding in the pure mountains on an atv if they arent used to it i could see them being more skittish
