No, the pun is not intended; The Daily Cardinal reports one of the main reasons the Occupy Madison street-use permit was not renewed was because a number of them were whacking off in public. Indeed, the behavior was so bad that a hotel next to the former occupied site felt the need to escort its employees to and from bus stops.
Another item that Madison officials had an issue with was the lack of restroom facilities. They reportedly are refusing to issue another permit until and unless the Occupiers secure some.
So, what did the Occupiers do? They marched down the street to Olin Terrace, on the shore of Lake Monona. Note the lack of restroom facilities or all-night hours in the city park.
The Isthmus notes that the expired/non-renewed permit wasn’t sought with the entire group’s up twinkles, so I doubt that the move to Olin Terrace has legal blessing.
The other reason for the move can’t exactly be discounted either. Madison’s Freakfest has been known to get quite violent.
