This is just a heads up to anyone visiting downtown Portland this coming Sunday, March 18th.
A "Peace March" has been organized with crowds possibly 30,000 (according to The Oregonian). Generally the affected areas are the South Park Blocks (rally before and after), but the march will block streets for a portion of the afternoon. I found a map at "pdxpeace.org" (not an endorsement...it was the only place I could find a map of the route).
Regardless of the politics or whether you wish to join in, I thought it would be a good idea to let visitors know what's going on this weekend.
