Now, I don't live in the city so maybe I am not as smart as you guys who drive 45 miles to work one way...but here goes.
I used to just go out WITHOUT using scent killers of any kind. It got to the point where the yotes would "hit a wall" and run every time I got winded. Now, after a few years of using scent free deodorant, shampoo and soap I have almost been run over by yotes that should have seen or smelled me. Oh yeah, I still get winded from time to time, after walking 5 miles or so you're going to put off a scent, but it gets minimized somewhat and that is an advantage I am willing to exploit. I believe they work to some degree and since they are inexpensive, where's the harm?
