Users of a park are fighting over who gets to voluntarily clean it.
The above link is to a Boston Globe article about how dueling volunteer groups are battling over the right to care for the park their way.
This is kinda ridiculous. And from the article it appears that dog off/on leash status is the problem. It is amazing how some people can become seemingly overly petty and vicious about benign issues.
EDIT: sorry, the article's site now seems to require registeration.
