We went hiking at Siouxon Creek this week. It's about an hour and a half from here... half an hour from our house in Portland till we get off the free way, half an hour going through Battleground (seems like ugly urban sprawl to me), and half an hour driving on US Forest Service Roads (beautiful but not great roads). The hike is lovely. It follows the creek and what a creek! The water is high because we had a lot of moisture this year.
