I have some really heavily traveled trails that do just that. In one case it fades completely away as it enters a white oak flat that also has more wintergreen than anywhere I hunt and they seem to love it. It doesn't make them taste minty though.

The other trail fades away as it enters a big swamp. I just attribute it to them speading out before they bed but that is just a guess.

I really believe that in areas without agriculture they meander more than if there was a solid local food sources. My deer wander all over the place and bed in different areas consistantly. Geez they are confusing.
