Lynn,
Remember that at one point we owned the HQ building in Denver outright, no mortgage or anything.
Then a decision was taken to sell the building and lease it back. I do not recall the reasoning behind that.
I agree that no good reason was ever given for moving to Topeka other than Steve Johnson wanting to be there. IIRC, someone said it was his hometown.
If anyone thinks Topeka is the greatest place to live, please speak up.
