i realize its not the best thing for the environment. but, a couple of squirts from a can pale in comparison to what the typical outboard motor spits into the water every second its running. additionally, they actually make scents and injections that are completely legal and they probably aren't a whole lot worse for the environment. definitely not a whole lot worse than some of the shit i've seen used for catfish bait. so, if you think it catches you a few extra fish, squirt away as far as i am concerned.
