The police told me that since he has been warned time and again to stay off the property, even without signs, its considered trespassing.
There ARE laws around here about cleaning up after dogs (I always take some dog baggies along).
The other thing is I kind of wonder since the city office doesnt know WHO this person is, that maybe he doesnt have his dog licensed either.
This would be a whole lot simpler if he would have just stayed off the property. What he gets from it, I dont know and probably dont WANT to know how that kind of brain works....
