Additionally, consent is not required for oral communications (e.g., in-person conversations) where the speakers does not have a reasonable expectation of privacy in the communication. See Ohio Rev. Code § 2933.51. This means that you are free to record a conversation happening between two people in a public place such as a street or a restaurant, so long as you are not using sensitive recording equipment to pick up what you otherwise would not hear. An excerpt from http://www.citmedialaw.org/legal-guide/ohio/ohio-recording-law So I interpret it as anywhere you are that you do not have the expectation of privacy (i.e. in front of an open window in your house, your car, a public venue, sidewalk, mall etc.) So you are good.
