I stopped by Harbor Freight today to pick up a set of expandable pruning shears for my Dad and while carrying I had no issues. A few customers took notice but said nothing.
On the way home I stopped by John Deere irrigation to pick up some goof plugs, again with no issues. The manager did ask "What's with the gun?" and I replied with "Oh, I open carry", which prompted me to give him a business card and participate in a small talk about how only gun stores seem to be making money right now.
