Location with European perch

Went out on the ice yesterday and had my best day of the year. I caught 13 perch on orange teardrops. Dead sticking all day. They didnt want to chase they just wanted it sitting there. Theyd come up and Id get one or two at a time. Then they would go back to the bottom. A little while later theyd come back up and Id get a few. Not a lot of size but it was still fun.
