A few years ago, Mensa had its Annual Gathering in Disneyworld.
For $140, thay rented us S.C.U.B.A. equipment, including a wet suit,
with which some of us went swimming in the huge saltwater pool
of the Coral Reef Restaurant in EPCOT,
http://disneyworld.disney.go.com/parks/epcot/dining/coral-reef-restaurant/
one of whose walls stands about 8 or 10 feet high,
with glass windows on one side of which r large, beautiful,
colorful fish, sharks n large tortoises and on the other side
abide the culinary hedonists of the said restaurant.
Thay have more than 80 different species of tropical fish (not on the menu).
I love that restaurant (delicious seafood @ modest prices)
and for years, I enjoyed the beauty of the fish while I was dining.
I was very happy to be on the other side of the glass looking into the restaurant,
whose customers were taking our pictures and waving at us.
Its like,
as long as u r under the surface of the water:
u can fly like Superman.
That was fun; I recommend it.
