Certainly, you should read up on Oregon's laws and know them inside and out to the best of your ability. If you just want some practical application information though, check here at
MarkedGuardian's YouTube channel. The owner of the channel, Warren, has spent about the last year going throughout the state while open carrying various weapons, but usually not just a handgun. He carries an AR15 at times, a .22 MP5 look-alike, and sometimes wears MOLLE vests and drop-leg tactical holsters. His mission is to draw attention to himself to educate both the general public and law enforcement about what is legal, and how your rights in Oregon are protected (or not, as the case may be) by your legislature and local LE agencies.
Before anyone chimes in to take note of Warren's irritating voice and excited sounding speaking style, he has a speech impediment that he freely admits is off-putting and often taken by LEOs as indicative of an "attitude." But he knows the law, always stays within the law, gives props to LEOs that treat him with respect and by the law, and points out every violation by them that they make. There have been times where he has made LEOs aware that he does indeed have a speech impediment, but the LEOs who have already misunderstood or ignored his perfectly valid arguments because of his voice have rarely, if ever, taken that into consideration as the contact proceeds.
Some people enjoy his videos, some hate 'em. I fall in neither category. I glean what information I can from them and discard what doesn't apply to me in my state. The guy is trying to do good works though. I don't see anything that suggests that he doesn't like cops or that he just enjoys causing trouble. What he enjoys most of all is being able to walk down a street and either be ignored by local LE because he isn't doing anything wrong, or he also seems to enjoy talking with cops as long as they remain friendly and respectful of his rights. Anyway, to the OP, check him out. You will learn a lot about both the law and how it is applied and enforced in Oregon.
