I'm sure there will be some lure/bait answers, but what is the smell that hits you deep? If you were a wooman (spelling intentional) trying to court me, bathe yourself in Hoppes #9, or (a close 2nd) boiled linseed oil.

Shotgun shell freshly shot

Castor. skunk, or fox. Love 'em.

Moosetrot

Can't say on here

Rain, puppy breath, shotgun that has just been fired, campfire, my dog's head, waxing traps, freshly brewed coffee, back straps on the grill, the prairie on a crisp morning.

A Chinese Food Fart ??????

Bacon frying,
Damp musty smell of leaves in the fall,
The Sulphur smell of a long awaited rain.

When I was cleaning guns and my boy was young he said dad what’s that smell I said hoppes #9 and if your lucky you will never forget it. I’ve always remembered it from my dad

Working walnut, the pungent cloud after shooting the smokepole, the river motoring upstream on a cool august morning

Elk musk and summer rain

New mowed hay! A gentle spring rain. Mast’s Muskrat #2 (wild cherry).

Red ear clover in bloom. Smells so sweet.

Spring rat castors.
Black hashish

A whiff of skunk, gunsmoke, warm butterscotch, beaver castor.

I'll second or third the smell of just-fired shotgun shells.

Baking bread.

Freshly cut grass.

Line-dried clothes.

Wet leaves in fall.

Fresh coffee brewing
Mesquite fire on a cold wet day
Leather

Warm dog, puppies, marten skins, cottonwood buds in the early spring.

Golden rod dying off sends a smell that signals trapping season to my brain

Mink, love the smell.... wife hates it

Skunk, smells like money....wife doesn't mind it lol

Napalm in the morning
