A bank is not included in that list of illegal to carry? What about government buildings?There are only a few places illegal by rule of Indiana law to carry. From memory: The Post Office, A lake under control of US Corp of Engineers, Schools, Churches (if being used as a school). I think that's it.
As above, if they don't want you to carry they can kick you out. But you won't be subject to arrest unless you refuse to comply and are tresspassed.
Keep it covered and keep your mouth shut and you should be ok.
