I agree with everything sloch24 said, in addition when we talk about the cans were mostly just using them as a refreshed for location. Most of the cans mark the perimeter of the camp perry firing range. The 3 most important things you should look for is water clarity, depth, and weather conditions. Pearch "usually " hang out in depths less than 25', than can b caught in deeper water though. A nice day with wave action of 1 to 3 footers has worked well. Having said all that when u get to the bait store ask where there catching them. It will probably be within a few miles of shore.
