Yeah, it's harder because you'd be floating on acid rain

  Isn't the acidity normal in the upper atmosphere? Though I suppose up there the advantage of greater buoyancy might be lost.

    At about 55 kilometers (where it's close to 25 degrees C and maybe 2/3 of standard air pressure) there are clouds of sulfuric acid. I believe you can avoid them by going higher, but then you lose the appeal of having earthlike temperature and pressure.

      Well, H2S04 provides you with many useful elements if you can process it. :)
