But they don't work. My mom lives in a community with a whole bunch of retired people. These deer whistles were must have on the pensioners' mad mod lists a couple of years ago. Until a) two drivers with whistles on their cars hit deer within a week; and b) my mom was riding in a car with the whistles, and a herd (10-12) slowly walked out in front of the car. It was almost like the deer were looking around, "what's that sound? I must get closer. . . . "
Anyway,
if anyone DOES find brush guard / bull bar / 'roo bar for an A4, let me know. The wagon needs one for collision protection; mounting of driving/fog lights; and a point to secure the bow of the canoe when I have it on the roof.
