High Line, New York -- Challenges

 * public meetings revealed desire to retain wild character and preserve site relatively as-is 
   but popularity of High Line may not allow for this

 * plantings 'reflect' previous landscape but are intermixed with new species 

 * paradox of values: recreational vs. ecological

 * retained tracks in some places but the 'wild' is gone 

 * graffiti policy wishy-washy: volunteers paint over graffiti on adjacent properties with 
   owners' permission - some give permission while others do not, leaving the site neither clear of 
   graffiti nor with a deliberate appreciation of it
