This is happening in the city in which I live:
Walk by this park every day. The man living in the trailer is completely harmless, respectful and clean. During the day he exercises in the Community Building (which is like a free gym/meeting place), and rides his bike. During the night he performs on the main downtown nightlife strip, which is only a few blocks away from his trailer. College kids give him spare change for his busking and that's how he's carved a life for himself.
The article itself is surprisingly fair, including quotes from the man himself. And here are some parts that are interesting:
"Tanner does have an acrimonious history with Lawrence City Hall. Most notably, Tanner was responsible for building a homeless camp on city property near the Kansas River, just north of the Santa Fe Depot. The city razed those structures in 2008, and Tanner has said repeatedly that he has never forgiven the city for those actions."
"Mayor Schumm said he thinks there are potential health concerns ... such as the potential for inappropriate disposal of sewage."
What a cute way of calling him a dirty piece of shit.
