[GoT] why didn’t the Targaryens ever go beyond the wall?

So I’m currently read the world of ice and fire and was wondering why the Targaryens never tried to conquer the wildings? Targaryens ruled Westeros and had dragons for centuries before the dance of dragons killed most of them. Did none of them think it would be worth it to at least explore what’s up there? They had been used to dealing with with hostile natives with a home field advantage (the dornish) and seemed comfortable enough with the dragons to fly the long distances require. The least they could do is run a bunch of recon flights from winterfell to get an accurate map of their kingdom. Seems weird they had seemingly no interest in that part of the continent.

Mostly it's for the same reason the Starks haven't conquered the Wildlings.  It's a lot more trouble than it's worth, they have a massive wall, there isn't a stable governmental structure like Dorne has, and the Night's Watch is an incredibly effective way to dispose of the unwanted.

The dragons can't do recon, they refuse to go into those lands.
