The one thing mentioned above that will get you in a trick as a NON resident is the Aquatic Weed permit. That's $22.00 as stated but you better not get caught in Oregon with a boat without it on your person.
There's some word out there that the Oregon Police will be pulling out of state bosts over to check if they appear wet etc. Nothing wrong with the idea behind it but don't let it be a revenue producer for them by ignorance!! It really hasn't been talked about much?? Just my $.02
