My wife is a pretty good "outdoors person" more so than most women today but sometimes there are holes in her knowledge/common sense.
She was cleaning out our "gear' closet and drug out a creel. We have no had a chance to do any fishing in three years. In the creel she found a jar of fish eggs. She OPENED IT
then, when the aroma hit her, she DROPPED IT
We have just invented the "Ronco Gag-o-matic". If I could put it in an aerosol container it would be a combination vulture bait/Defense against human predators spray. No human can focus on anything in the presence of that odor.
When the dog runs up, rolls in it coughs and runs away, you are on to something.
