I, personnelly, don't open carry, but they guys aroung here seem to wear a short coat that can't cover the gun. And you have to take the gun out of the holster when in a car. On the passenger seat or dashboard is the general concensus. On the console between the seats could still be considered concealed from PLAIN view.
I carry concealed with the license and it's about the opposite. As weather gets warmer you have to get more creative in where to hide a gun. Winter is easy and summer for me in not much more then a t-shirt and shorts. I've found the smartcarry able to conceal in nothing but shorts.
Oh, and welcome to the forums.
