Quinte Fishing

Went out sat,630am, 3 guys fishing mouth of Sherman's. We caught a bunch of 6inch walleye, couple eaters and biggest was 3.5lbs, also a herring. After approx 10.30am fishing dyed off with just a perch and a few small bites, wasn't marking to many fish and continued that way till 6pm.
Noticed that a small fishing village had formed out from mouth of Sherman's! Just curious if this was a hot spot that day or what??? Couldn't believe how many guys out there..also how thick ice was ther we were on approx 8-10 inch.
