I would suggest re-reading Indiana Code on prohibited places to carry. There are a few other areas where carry, OC or CC, is prohibited.
Yea any court building, but thats common sense. Other than that I havent found any other places. If im wrong can you send me a link, maybe im not seeing all our gun laws. Here is where I read the gun laws.
