I'm getting ready to head to the Smoky Mountains for a week of riding. I live in Florida. Down here we don't have a lot of deer, tourists and grayhairs but not many deer. A couple of guys said I needed to install a couple of deer whistles on the bike to keep them away from the road. I thought my loud pipes would do that. Do they work? How many of you that live in the highly populated deer areas have these on your bikes.? Where did you mount them? Seems like a waste of money.
