Lou, . . . there is just a little bit more information you need to know to safely and legally cross Ohio.
That CCW handgun has to be in plain sight to the officer who approaches you in your vehicle (if it is not in a locked box, or a locked glove compartment). That does not mean laying on the seat or on the dashboard, . . . it must be on your person, . . . and the law itself even stipulates it must be in a holster.
I would not speculate on whether Officer X would allow Mexican carry, . . . or whether the lockable console would work, . . . I don't use either method.
You also need to have your CCW permit and DL and registration and proof of insurance, . . . because you will be asked for all of them.
Immediately after the "good afternoon, driver", . . . "good afternoon, officer" pleasantries, . . . make sure you inform him that you have a loaded handgun in the vehicle, . . . where it is, . . . and hand him your paperwork.
To many our law may sound goofy, . . . but try that in Illinois, Wisconsin, Canada, or the UK, . . . and Ohio sounds pretty cool.
May God bless,
Dwight
