I used to feel the same way about Southern Illinois. I would hunt old parks and homesites, and find lots of clad, but no silver. The first "good" coin I found, was an Indian Head in a creek. What I noticed, was I was going very slow in the creek compared to dry land hunting. I started doing that in the parks, going very slow, rescanning every odd chirp from the AT Pro as well. I have only found 16 silvers this year, but I feel like there is a chance every time I go out. Another thing I do is criss cross hunt. There is an abandoned soccer field that I hit goal to goal, and the next time out I went sideline to sideline. (I found a 1940 Merc yesterday doing that.) The merc came up an 82-83 one way, but when I circled it from another angle, it was 78-79. Just some tips that I have picked up through trial and error. Good luck, and happy hunting!
