About avoiding airspace and cruising

Not the sicko kind of cruising, either.

A friend of mine bought a house on some large property about
six miles (linearly) away from a towered airport with class D
five miles around it (one protrusion for approaches that I'm not
concerned with).

She's having a barn built and I'd like to fly over and take some
pictures, but this puts me just outside of the airspace and
somewhat inline with where aircraft come in, a somewhat popular
route to arrive from.

This is far enough away that I suspect most traffic is still at
upwards of 2000' or better. I've flown over and found her house,
but it always makes me nervous. Twitchy as a chipmunk in a cat
house. Well, not a cathouse, really, but still.

What's the safest way to do this? (Yes, my piloting is young yet,
but I'm still proud of it.)
