Wow... And I thought my trespassers looked like rednecks!!!

It's Kalifornia what do you expect?
Any possibility these guys have a pot farm or a few plants on your property? If so they could be dangerous. The one looks like he's done some prison time to me.
Personally I'd nail them with a restraining order. I wouldn't tolerate strangers snooping around my property. You could end up with another break in.
BTW I'm disappointed one of them wasn't Cody Lundin of Dual Survivor.

He goes barefoot too.
