Yes I understand the top point but was hoping to find a way to use it with my 3rd vehicle as well.

And yes, Oregon has a state parks pass for $30/year or $50/2 years good for all state parks.

Seems fair. I would rarely use it for my wife's car anyway, but just wanted to get the lowdown from folks who have experience.

Yes this. My wife's car would rarely be used but there are times where I could see her going across the river to Beacon Rock while I'm at work with my car.

I just wanted to see if anyone had not filled theirs out and got away with it.

The cops tried to get the story out of the victim while they were still alive, but they kept blubbering.
