(Undated)  --  Oregon is 26th on a list of states with the highest percentage of McDonald's restaurants.  "24-7 Wall Street" says the fast-food chain is nearing saturation in the U.S. and is trying to draw more sales out of each franchise while closing those which are underperforming.  In Oregon, there are 205 McDonald's locations, or five-point-two stores for every 100 thousand people.  Washington ranks 34th in the nation, with four-point-six McDonald's for every 100-thousand people.
