Demonstration in Eugene

There were hundreds of demonstrations in the U.S. yesterday against gun violence and the lack of regulations on assault weapons.  The one in Washington D.C. was the largest.  Estimates of the size ranged wildly--some activists claimed 800,000 but I think an imaging company with some expertise in estimating crowd size from aerial photographs put it more like 200,000.  Estimates of the march in Eugene also varied greatly.
