First off, welcome to the forums and to the state. I can't help much with the choke question, but as a fellow transplant, it can be a little overwhelming where to start looking for info as to where to go. A good first step is checking out the ODNR website for local WMA's. They have a regonal interactive map that can help you track down what is closest. Next step would be to make phone calls and troll the forums for references to those areas closest and maybe post with specific questions about those areas. GW's and wildlife area personel are the best resources early on in the search. Turkey hunters tend to be shut mouthed about specifics, but you may be able to get someone to help you out with some info. I'd offer you something directly, but I'm in a different area of the state. All I know is you have lots of birds in you neighborhood. Lastly, wear out some boot leather. Get out in your choosen spots and look and listen. Preseason calling should be limited to locators like crow and owl. Get familiar with the terrain and nail down the locations of as many birds as you can. Roost the night before the opener just to make sure your chossen bird is still there and hold on tight. Good luck and looking forward to hearing about your success!
