On saturday morning i went to the costco near main street and headed back to waldo/brookside via gillham. I ussually take gillham to 45th to oak to make my way South of the plaza. Oak was closed south of 45rd. I then proceeded to try and figure out an alternate route. It literally took me about 20 minutes to figure out a way out of the closed streets. Total shitshow. I must have seen about 25 cops devoted to shutting streets down in the area. I initially thought there must have been some kind of race or something, but apparently not. I got to the point where I was checking twitter/reddit because it was such a cluster...tons of cars having no idea where to go, but nothing. my final guess was that there was a manhunt happening and the cops wanted to create a perimeter.
