hey look at this

Just from and old fishing trip when i was a kid, my father and i sat in a crappie house for hours with outta bite, and there were to old ladies sitting accross from us that were catching one after another. so my father told me to go and get a squirt of that glittery green kind and i ran back over and dropped my line in the water and it wasnt 2 seconds and i already had a fish. for the rest of the night it was about that way untill the old ladies left and took ther "working" scent away. I do believe it makes a diference in slow presentation with live bait and i agree with the cover scent theory
