Enough is enough...the Calgary Zoo needs

[awa1979]

Of the zoo's I have been to in Canada (Edmonton, Vancouver, Calgary) the Calgary one is the best with the most suitable enclosures, the Vancouver zoo is the worst.

Of the zoo's on a world wide scale, San Diego Zoo is by far the best I have ever been to followed by the Sydney Zoo.

This seems to be a an accident that one really could not predict.

I would however be interested in why the rays died.
