Offroading 'lite' near Beaverton?

This is my first new vehicle, and I have zero scratches, dents, or dings. I'm quite proud. However, I also bought this for a reason - I like to go places where my car couldn't!

I'm not ready to fully subject my truck to the freaky offroad stuff some of the guys around here do, but I'm looking for some good undeveloped roads near Hillsboro/Beaverton, Oregon etc. I used to live in Salem, Oregon, and would drive out to Mill City (next to Detroit) and wander the logging roads in my friend's truck, and I'm looking for something similar.

Anyone have any ideas?

 

I also live in beaverton, My cousin has a farm out by salem i like to off road by the willamette river over there or you could go up by Stimson by the lake up there, there are some fun roads up there

 

I'll try scouting around there, thanks - getting to Stimson Mill chops off about 20 minutes versus going to Brown's camp!

 

Bump

 

I broke the dam

 

Says the guy who has less mud on his truck

I still don't know where Stimson Mill is, lol
