Not sure if your numbers are right, but I had a terrific day Friday about 5 miles from that spot. Went to those numbers after seeing your post. No boats. No fish on the fish finder. No nets. Saw lots of glare off windshields to the WNW. Big pack of boats at 34.5-20. And lots of perch. Screen was as full of fish as I have ever seen it. Got a limit in 2 hours. Lots of 9-11 inchers. There were nets about a mile SE from the pack.
