I wouldn't let anyone fly on my private property without ensuring the other flyers had some way of protecting me (insurance).
AMA is easy. "show me your AMA card and you can fly".
Private insurance is hard. "Bring me your policy and show me where it covers an airplane accident on my property, I may need my attorney to look it over and, oh, and when does your policy renew"???????
Their liability insurance is of little use to you...you will need your own in the case as you mentioned...I know you must know that.
