I've shot up in the fossil bed area and have seen those signs. I have friends that shoot down there all the time, but I usually shoot down river more. I checked w/ Indiana DNR and my own CO's and noone seems to know who put those signs up as there is nothing in either state's laws to back them. I gave up bass tourneys about 15 years ago and started getting into bowfishing heavy. Now it's all I do. It's a blast for sure! If you like archery....and fishing...what's really not to love about it..LOL
