I did time in Yakima. Two and a half years for a job there. Wife hated it because it was away from her family, but we still think fondly of it at times now. Granted, we lived out closer to West Valley with a south facing large window looking out at Ahtanum instead of living down in the ghetto (money is why I took the job and moved out there), but Yakima really does have it's good spots. I miss the Rueben at 2nd Street Pub (one of my top 3 Reubens all time), Russilo's Neapolitin pizza, Zesta Cuccina (better than the Portland one by far), That joint out at the golf course in the valley, etc. (yeah I like food OK?).
You'll find things to do. Gotta look outdours though.
