Indiana is very good in fact. We do not have open carry as such. However, our CC permits (called "License to Carry a Handgun") makes no stipulation on how that handgun must or can be carried. You got the license, carry it any way you like...open or concealed. We have none of that business where if somebody sees you CC weapon you're violating. We do have to have the license to carry in a vehicle but again, there is no stipulation on how to carry in that vehicle if licensed. And, that license is lifetime! Not very many gun free zones here either...just the usual ones (court houses, pro sports venues, post offices, and airports is about it). None of that business about no CC in a bar or restaurant although there are plenty of bars that wouldn't let you in if they knew you were carrying but that's gonna be between you and their bouncer...not a legal issue. We have none of that "official state sanctioned no weapons" signs either...that legally prohibits you from carrying if displayed...none of that here.
Indiana probably lacks the ingrained hunting culture that some of our close neighbors have (Kentucky, Michigan, Wisconsin) but there are certainly a lot of hunters here. Thus the slightly lowered participation in an active gun culture. Indiana is very flat and very fertile and thus the place was plowed up as fast as they could. So lots and lots of farmers back in the old days had guns but they were not the dedicated hunters in most cases that we see in the western states for example.
But as far as freedom goes vis-a-vis firearms, Indiana is really good, the police are not a problem for the lawful gun owner in just about all the cities including Indianapolis, politicians on both sides of the political aisle are pro-gun, and there are some very good gun shops here.
