Indiana is a great carry state. We recognizeANY state-issued License toCarry(but not the IL FOI Card - it's only for IL residents to PURCHASEweapons).You can OC or CC, just watch for signs that say "NO FIREARMS ALLOWED" and stay away from Courthouse & Post offices. Bars are OK. You shouldn't have any troubles.
Don't shoot anyone that doesn't earn their share of lead. Don't piss off any LEOs. You'll be good to go.
