I appreciate your reply Jay.  I've really struggled w/this issue.  How do I feel.  I will validate that it is uncomfortable in a public area, w/family, trying to enjoy the lovely day and a group of 'vagabond' types (we really don't know their circumstances) and they're obnoxious, rowdy and drunk.  That's not right and they should be removed.  

I remember the 70's and 80's (early) and we had so many more parks and ALL of us enjoyed the space.  All folks.  Except then? We didn't suffer w/the 'self only' issues that are so prevalent the world over.  Lost souls, no good jobs, cell phones, texting, computers.  We have a social disorder going on; I want you to have the luxury and good fortune to enjoy the parks as I've described.  I also want those who are so different and 'hurting' (?) to have a place too.
I just don't know what the answer is but my neck hairs bristle: deserve, right or privilege.  None of us should feel we're better than others.  I've no walked in their shoes.  

peace
