Dog urinating and defecating on your site while owners watch

Ever spend time on any of the Coasts camping?? We had a flock of Pelicans, Sea gulls and some other big ugly bird try to dive bomb us one week!! Turns out I threw out some meat trimmings in the garbage and these things wanted it,, they made a mess of the picnic table,my trailer and my PU!! We laughed because they would actually try to poop on our heads when we went out!! We have learned NOT to get a spot any where near a dumpster!! Oh well,, I hear that in some countries,,getting pooped on by a bird is good luck??
