I have to admit I see Dan's point.
It is not clear from the context of your reply "eh? your joking right" what you mean.
In all fairness, it makes more than perfect sense to me that, if he's going to find a suitable field, he's going to ask the owner for permission. That's how I interpreted his reply -- it is precisely what I would have done.
I do now, because, seeing the discussion, I see how Dan might have completely NOT understood why you txt "you're joking, right?", and would probably have thought ok, let's give it a miss... and I don't think it's really fair to put the blame on him.
The foot-in-mouth removal tool seems like just what the doctor ordered here.
