I tried the Nature Preserve first and found out it was extremely spotty ice. It was anywhere from 3 inches to a 1 1/2 in places. I couldn't get to my go to spot, so I hit up Long Island instead (first pull off). The ice was good and the fishing was good. At first it was a struggle to find the fish, but once I did it was bite after bite. I ended up with 5 nice gills, but like everyone else I had to weed through the dinks. Also caught a dink bonus perch. LOL I was going to post measurement of the ice, but by this time tomorrow the ice at the nature preserve should be good too. (As always check your own ice, make your best judgement, and be safe)
