I would MUCH prefer to carry OWB for any number of reasons. I just don't want to deal with the inevitable MWG calls.
You assume there will be any. I've carried just about everywhere openly, and have never had a man with a gun call. This includes all around Purdue's campus ( off campus, in surrounding west lafayette ) even going to wal-mart at 5-6pm during it's busiest hour. Not a single complaint, call, or anything.
Infact, a rather pretty girl smiled at me and said hi.
