Hey Piero, we live in unincorporated clark county, out in the foothills. Its a great place! Real close to state forest land. Streams are healthy. Lots of trees. One downside is that most people seem to move out here to keep to themselves, something which i grow more and more confused about.
Where we are land is usually $30,000/acre. Yeah its super expensive compared to cowlitz but there is an upside of higher population densities(maybe this is a downside to some), and proximity to portland.
There are several properties within walking distance of our house that are for sale currently. Mostly 5 acre parcels without much improvements. I'm always trying to attract more permie neighbors out here.
