Where is the best place to install deer whistles?

I'm putting deer whistles on my 99 Corolla. I'm aware they quite likely don't work, but after hitting 3 deer in the last 7 years, I'll give it a try.

Any suggestions for where to put the whistles? Should I put them in the grill? Alternatively? Should I put it on top of the car near the hood?

On the wife or girlfriend. When they are coming toward you say"Is that you deer?"

As far as an snarky internet responses go, this one made me chuckle. Well played ToyBoy
