No crack being smoked here,there are fresh water jellyfish.While not a true jellyfish but a jellyfish to anyone who sees it none the less.The difference between the fresh water and salt water is minimal at best.My brother told me he seen some in patoka about 6 or 7 years ago and i thought he was full of it just like most of the people i tell it to today.I was also told the water had to be really clean,which doesnt explain why i seen them in harrods creek but my buddy {bandit1} spotted them and i looked down and there they were,if still not a beleiver call the falls of ohio biologist and verify it yourself.
