It is not clear from your post where in Wyoming you went. In fact, I only assume you were in Wyoming since your post is in the Wyoming topic area.
I just returned from a trip from Rapid City, South Dakota to Casper, Wyoming. Was a week long trip. I open carried most of the time without any difficulty.
Was coming out of a restaurant in Lusk, Wyoming when an older couple in their 50s who had been eating the same restaurant were waiting for me.
They asked me why I was carrying a gun. I replied with the question "Do you wear a seat belt when you get in your car?" "I assume you don't expect to get in an accident but put it on just in case" Well that is why I carry a gun, just in case.
They were pleased with the answer and it turns out that they were from AZ visiting WY. They were suprised to learn that I was from SD but openly carrying in WY.
They had been considering getting handguns themselves for some time now and our conversation convinced them to buy guns upon their return to AZ.
Other than that I had no incidents openly carrying. Most people did not even notice. For those who did, I may as well have been carrying a cell phone on my hip.
