I don't think you can trick a hogs nose.
this is right on the money!! If they get down wind you are busted
I shoot a lot of hogs down wind of me. I don't like to because the odds of getting busted are definitely increased, but just because the hogs are down wind doesn't mean you will get busted.
Even if you get busted, doesn't mean the hogs will necessarily move very far.
Hogs may have the capability of sensing your smell from a great distance, but whether or not they are exercising that capability or acting on what they learn is a whole other matter.
There I hunt they hang their teen age son's smelly shoes from the feeder, swap out a fresh (?) pair when filling the feeder.
The smell is always there and is associated with food.
