Search "How many states can you get legal in" for an interesting discussion about 50-state carry.

Be aware that OH doesn't recognize TX CHL and they have some odd laws of keeping things separated in different compartments of the vehicle as well as locked up etc. There's a thread on here somewhere, "legal carry in every state" or something like that and you'll find info on creatively covering CHLs in various states. I'll be in OH this summer and it looks like getting my UT carry (reciprocity with OH and available to Texans) is going to be the easiest way. OH AG e-mailed me back and said no way to non resident permits.
