Cobra,
The first place to start would be the ARRL, the National Association for Amateur Radio -
http://www.arrl.org/ . There you can find information about local clubs and testing opportunities. By clicking on the EDUCATION tab you will find information on Getting Started as a Ham. That page will also let you search for local ARRL affiliated CLubs who may offer Entry Level classes and Testing. Since you said that you are in OHIO I found the page you should see-
http://www.arrl.org/FandES/field/cl...p;selsect=Show+clubs+in+selected+ARRL+section . That URL will take you to a page with all of the ARRL clubs in OHIO. Scroll through the list and find a couple in your area. Contact them and see when they have their meetings and when the next class starts to learn what you need to know for the Entry level exam. Now is a good time to drop in to a club and introduce yourself. The summer months are full of ham related events not the least of which is Field Day the last weekend of June. This would be an excellent time to meet many local hobbiests and even operate some radios under their guidance.
Meanwhile to listen in to some of the regular nets you can see a list of OHIO Nets at this URL-
http://www.arrl.org/FandES/field/nets/client/Sresults1.html .
If you want to see a map with all of the repeaters list in every county in OHIO then you can click on this URL-

I hope that I have been of some help.
Good luck,
Steve,
