I think technically you are not supposed to used "discounted" (faculty) tickets unless you are
OSU staff or faculty, or unless the ticket holder 'upgrades' to Public Tix. So I guess technically, they could run into some problems (i.e., not faculty/staff trying to use discounted tix, have an expired ID, you cannot upgrade discount tix on game day).
But I've seen other similar questions where many many people have said they've done this themselves or let others use their tickets and IDs, and I don't recall anyone saying that they ran into trouble.
So while I'd be a bit nervous attempting this, making such a long trip, without an 'air-tight' plan, others will probably tell you not to fear.
There is also a 'Faculty/Staff Tickets Policies' link at the
OSU Athletics site as well as the Student Tix tab with more info.
