RE: Orange Tape
I've put orange tape around a tree on wildlife areas before to make my blind location more visible to other hunters - bow and pheasant. If I ever went there during gun, I'd cover the whole blind in orange duck tape. Better yet, I'm never going to have to try that.
As for survey marking, we've had land surveyed and from looking at other surveyed land in our area, it's all pink plastic ribbons. I've never seen any surveyor use orange tape. But that's here.
