In FL we're allowed to carry different weapons besides simply firearms. We can conceal large hunting knives, clubs, batons, and other weapons as well. For when you don't need lethal means of protection.
I have no problems concealing when I'm somewhere other than FL. I'm so used to IWB that I don't even think about it. I've never had the desire personally to Open Carry. It might be an interesting experience though. I don't see myself leaving the state any time soon though.
