so it seems the number one problem dog hunter face....... is ourself.
You hit the nail on the head!
One of my biggest issues hunting these "city hogs" is convincing these HOA's, developers, boards of directors, local govt. agencies, etc... to let me bring the dogs in to help solve their problem. They all want you there... but no one want to be held responsible.
Once you get established, do everything you can to earn a spotless reputation. Good references are priceless in future properties you try to obtain.
Also, try and work with local law enforement. I work closely with the sheriff's dept, game wardens and constables... having them on your side and for references is a major plus.
