It would depend upon the brand and model of the tape. Some might be okay, some might be victims of sticky-shed, which would mean that they need to be baked just before playing/transferring to another storage medium.
Fortunately for you, Ohio was lousy with recording studios, so you should be able to find someone to transfer them for you. Otherwise, depending upon what part of the state you are in, Pittsburgh has a few studios that can handle the work. If you think that there is anything worthwhile on the tapes, take the time to find a well-maintained set of machines. You might only get one shot.
The most likely problem with tapes of that age that -don't- have a sticky-shed problem would be the edit points. Any splices probably will have dried out and the tape will have stopped adhering. You might have to clean and retape these edits, and the head and tails tape.
