The seven wonders of the natural world are the Grand Canyon, Great Barrier Reef, Harbor of Rio de Janeiro, Mount Everest, Aurora, Parícutin volcano, and Victoria Falls. Have you been to any of them? Which is your favourite?
Have been several times to GBR, mostly for work. It's stunning. Once had an Apartment on Hayman Island, from whose verandah I looked straight down the Whisunday Passage. Stayed there a week, & its' beauty never ceased to amaze me.
Still on 'bucket list' is Victoria Falls & Aurora Borealis! So too, Iguazzu Falls, Torres del Paine, Alaska Passage & Manchu Pichu! I'll get there 'one day'.
Flew in co-pilot's seat over the GC! It is TRULY awesome. Coming into land at GC airport is not for the faint-hearted!
