A few times I have OC'd down to Pendleton & Hermiston when I travel down that way. Generally I set up to do IWB OC before crossing into Oregon to stay within regulations. The reactions I've gotten have been mixed.

Last night was on the way home from Wildhorse Resort & Casino (sidearm was secured in center console of car) & stopped by the Hermiston Walmart Supercenter to do a bit of sales tax free shopping. While back near Home Entertainment I saw a gentleman carrying a small breed dog & right below the dog was an OC'd sidearm. Only reason why I noticed was cause of situation awareness & paying attention to my surroundings.
