“Dear PoPville,

I noticed from my window (Friday @ 8:24pm) people were posting signs. I couldn’t see what the signs said from my window but I took a picture of them anyway. This morning [Saturday] on my way to the airport I checked out the signs. They are all down the 1300 block of R st NW for “emergency” no parking with a reason “Shinola Detroit block party” starting Saturday at 9:30.

Can individuals really post signs 12 hours in advance for a “party” and subject citizens to ticket and towing charges and fines?”
