I won't comment on Ohio law as I am not an Ohio resident. I agree, the laws are very complicated to read and understand, as they are written.
The It's a Right, but don't try to use it or people will freak out, and then you will lose that Right mentality is strong in many. It's a Right, but but but but.......
Do a search on open carry maps and you should be able to find a few links to interpretation sites of your states' laws. Not as good as reading th law itself, but as mentioned not easy either. Keep in mind that what gets put on the Internet stays there for ever, so make sure you are reading current data.
An important thing to also look at is not only can you leave your yard OC, (I believe you can in OH) but what places in particular can you NOT go into in OH. That seems to be quite different in each state. Some are universal such as Post Offices, but many such as banks and taverns/bars vary from state to state. It's all way too complicated, especially when you start traveling across state lines.
Enjoy your freedom!
