If you are overflying Joe's paddock airstrip on the way into Mildura and 17 miles out without it marked on the charts or listed in ERSA, how the heck would you know it was there unless you happened to see it as you went over, and how would you know where Joe's place was if someone else gave a "10 miles inbound Joe's paddock" call?
Joe's paddock isn't a CTAF and I'll be on the Area.
