We were on an excursion to a lagoon west of Rio, and I could see from the coach to the south of the main road what I took to be a pair of airship sheds about 50 miles from Rio.
Looking on Flashearth, there's a military airfield near a town called Santa Cruz posn 22 deg 55' 48.2" S 43 deg 45' 6.5" W which has one airship shed, so where I got two from I don't know!!
