We haven't caught any yet this year, but the gravel/silt transitions are usually the best areas on the East side.  Without giving away my spot find my house out there (about 2 miles out and a little South), head NE about 300 yards and that is usually a good spot for late season perch.  I haven't been up for a couple weeks, but I bet some rentals will be put there soon if they aren't there already.  I'm not sure how good its going to be this year though because we usually get a few perch earlier in the year where we are.
