I don't mind open carry and from a liberty standpoint think it's part of our 2A rights. I plan to still carry concealed for the most part. The only advantage I see personally for me is instead of the required mouse gun to carry concealed, I can now strap on almost any size and go to town if I choose.
In fact I have a new Mernickle holster for my Uberti Colt clone that I'm considering. Now if I had an original Colt SAA (preferably case colored frame with polished blue barrel & cylinder along with genuine ivory grips), well... I'd just have to open carry that to show it off.
