Additional remedy is, for now, to post that property, and put your phone number on the signs. During last summer, I kicked off 12 people a day...and that was with the help of the sheriff. Ours is a private beach issue. Try to learn from your experience, I am a much better negotiator now. LOL God Bless, and remember, it will pass. Hope all else is well with you.
