Tim, your Lane  letter is a good example that even a good idea can be carried too far.  If Joseph Lane were simply the flaming Confederate that  you and Sue Polsbo depict I'd join you in demanding his name be removed from our county.  However, Lane was a mixed bag, and  there is much more to the  Lane story.  
Yes, he fought against the Takelma, but he respected them and they respected him.  Your claim he "owned slaves until 1878" is based on  a questionable interpretation of his relationship with Peter Waldo.  He did not run for "VP of the Confederacy," he was the Southern Democrat VP candidate. 
He made many major contributions to our state in his various roles as Territorial Governor, Territorial Rep, and Senator. 
In his old age he moderated his views, reconciled with old friends, and at the end Kincaid's passionately Republican Oregon State Journal concluded "Probably no man has done more for the welfare of the state or more enjoyed the respect and esteem of the country than he."
