A few years back .. the Town home Association that I live in ... the board members tried banning ALL types of ball playing because of fear of law suits ..
The home owners freaked out on them about that and they backed off
can't climb the trees or build tree houses either .. again insurance problems
Also, can't dig holes .. that's call destruction of property
Around my ... we don't have sidewalks and the only place to walk or ride a bike is on the streets ... not to safe there with the way the idiots drive up here
