Turkey... thanks for the shout out. Sadly I am not much of a "spot" giver as I like to arrive there and find no one else fishing them! Having said that, Presque Isle is full of big carp and if you know the kinds of terrain that carp like you should have no problem at all finding them.
The biggest challenge with carp on the bay is getting the right weather conditions for sight fishing. If you can't see them that is an awful lot of water to go blind casting to which is pretty futile for carp to begin with... IMHO.
Good Luck!
