One of the great things about Portland is that within about 2 hours any direction, you are out in the country and there is so much to do. You have Mt. Hood and the Cascades to the east, the Beach to the west, Farm/wine/Hops country to the west/south/Southwest (Central Willamette Valley and the Tualatin Valley), Mt Saint Helens to the Northeast and lots of small country towns in between.
I have had to readjust to city life over the past 6 years, but I still feel like a fish out of water here. I still knew how to get around, but the pace of life and the constant going of city life was and still is lost on me.
I spent 4 years living in the central Willamette Valley, in a small town in the middle of nowhere. Pretty much every day I miss the way of life I had there. I know of young adults who wanted and did escape the small town and exchanged that for the city life where as I would do anything I could to move back to the small town.
